Along with ice cream, tank tops, and plenty of vitamin D, flip-flops may just be one of the greatest benefits of warm weather. But choosing the right pair is not always as simple as it might seem. In this article, we will break down the different types of women's flip-flops as well as which ones are best-suited for various activities. Additionally, we'll discuss the different materials used to manufacture these open-toed shoes and how those materials affect both comfort and support. Finally, we'll touch on how to fit your next pair properly.

For a full discussion of each of the products, we mention in this article, be sure to check out The Best Flip-Flop Sandals for Women Review. This review includes side-by-side comparisons of 11 different women's flip flops, and it explains the metrics we used to rate each piece, including comfort, stability and support, durability, water resistance, traction, and style. These categories will help shed light on aspects that may be crucial in your quest to finding the perfect pair.

Types of Women's Flip-Flops


For this review, we tested pieces with light foam footbeds, molded or contoured footbeds, foot-molding footbeds, and novelty footbeds. The strap configuration on our tested models varied pretty extensively, though all had a thong-style toe-post at the front and no heel strap across the back. If you're looking for a sandal with a heel strap, head on over to The Best Sandals for Women Review. Manufacturers offer a wide variety of different strap configurations that can give your sandals a unique look and fit. We'll discuss these a bit more below, but first, let's dive into footbed types:

Light Foam Footbeds


The light foam footbeds found on cheap, bargain sandals are the least supportive and stable of the bunch. For many, these sandals are often either desperation or impulse buys (i.e. OMG, how did I make it to the beach without a pair of flip-flops!? …or… OMG, bumblebees on this $3 pair of flips!? So cute, must have!!)
As a general rule, we don't recommend this style of footbed. Yes, they're cheap, but they can foster foot problems you want to steer clear of, such as plantar fasciitis. They might be fine as a locker room shower shoe, but beyond they are not ideal. While we tested a few models with foam or partial-foam footbeds, those models more accurately fit into the next category, foot-molding footbeds.

We also feel it's important to take a minute here and break down the price-value side of things. Super cheap flips wear down and blow out fairly quickly, so if you're an avid wearer, you could easily go through more than one pair per summer. For argument's sake, let's just say three $7 pairs. At $21, you're already almost at the price of our Best Buy award winner, the Teva Olowahu, which we feel will last you at least two seasons (and very likely much longer).

After three years of spending $21 per summer on cheap flips, you're up to the cost of the OluKai Ohana, the Chaco Flip EcoTread, or the Vionic Tide II - all fantastic, super supportive models that will easily last for years. Even though these pieces are a bigger up-front investment, be sure to consider this breakdown the next time you're standing in front of the bargain sandal display. Oh, and don't forget that by buying one nice pair of flips instead of a cheaper "disposable" model, you're also putting less trash into the environment! Now that we've established why we don't recommend models with light foam footbeds, let's move on up the ladder to foot-molding footbeds.

Foot-Molding Footbeds


In our review, we tested several products with foot-molding footbeds, most notably our Best Buy winner, the Teva Olowahu and the Rainbow Single Layer Premier. Sandals like these have footbeds with EVA or foam/rubber compounds that remember the shape of your foot over time. Many people find this type of footbed to be insanely comfortable. When new, your foot sinks in just a little bit, and as you break them in, the footbed becomes an exact mold of your foot. Unlike the light foam footbeds mentioned above, EVA footbeds provide some shock absorption and support.

The greatest benefit of these foot-molding models is that they tend to be relatively affordable, but provide some of the perks of high-end contoured footbed sandals. In general, however, this type of flop does not offer stellar support or stability. In fact, some experts believe that a foot-molding footbed can exacerbate existing foot anomalies which can then lead to bone and joint problems. These are not the sandals that you want to wear on hikes or all-day excursions. Foot-molding flips are comfortable and more affordable than contoured models, but they're only ideal for general non-excessive use. That said, they are a huge step up from their arch-abusing light foam cousins. If you don't want to shell out for a high-end flip, at least do yourself a favor and opt for a slightly more expensive and infinitely more comfortable foot-molding model.

The lightweight EVA-foam footbed of the Olowahu is thick and plush and will mold to your feet over time  but it's not particularly durable or supportive.

Novelty Footbeds


We only tested one flip that properly fits into this category, the Sanuk Yoga Chakra, which has footbeds made out of real yoga mats. After wearing this model around for several months, we realized that novelty footbeds like this one are more about initial comfort than about overall performance. When the wearer slips them on, they do have that "ahhhh" effect that defined our comfort metric, but they often lack other important qualities like support or water resistance. Novelty footbeds are admittedly kind of cool, and they can be quite comfortable, but they also require the wearer to choose what qualities are most important. Before purchasing one of these flips, be sure to ask yourself how you hope to use them. If it's just a morning at the coffee shop or something to slip on after a workout, the novelty footbed should do fine. But if you plan to do more walking in your flips (even during around-town errands), be sure to look for something that provides a little more support and stability.

Comfortable? Yes. Supportive or stable? I mean... the footbed is made out of yoga mats  how substantial can it really be?

Contoured Footbeds


If there's one thing you take away from this section, it should be this: "Contoured Footbed = Support & Stability = Happy, Healthy Feet (even on all-day adventures)." OK, let's expand…in this review, all of our top performers had contoured or molded rubber footbeds. The Editors' Choice Birkenstock Gizeh, our Top Pick for Stylish Adventures, the OluKai Lala, the Vionic Tide II, our second place finisher, and the OluKai Ohana, our previous Editors' Choice all have contoured footbeds. Each of these sandals have sturdy contoured footbeds made with materials like EVA, PU, and leather that are difficult to bend in half down the middle. They do, however, bend in the forefoot, where the foot naturally bends. Next time you're at the store perusing flip-flops, pick a few up and try bending them in half. If it folds easily, it won't provide much, if any, stability.

Contoured footbeds also provide more support. Manufacturers like OluKai, Chaco, Birkenstock, and Vionic have designed their products with footbeds that are anatomical molds of the bottom of a typical foot. Since we obviously don't all have the same foot shape, it can be beneficial to try on different pairs of contoured flips to determine what is best for you. Some of the differences include heel cup shape, outer edge padding, and - most importantly - arch height. For example, the Vionic Tide II had the most intense arch support of all the models we tested because it has orthotics built into the footbed. This feature can be delightful for some people and excruciating for others.

Almost always, contoured sandals are more expensive. Their designs are more advanced and intentional than the simple foam cut-outs of other models, and they use sturdier, more durable materials to provide stand-out stability and support. If you're investing in a contoured flip, make sure that it supports the unique shape of your foot (continue reading our Fit section for more info on this subject). Even though we can never expect a sandal to provide the support and stability of footwear like hiking boots, flip-flops with contoured footbeds, (especially those like the Birkenstock Gizeh that have vast amounts of invested thought and research), can come surprisingly close.

Why We Suggest Contoured Footbeds


Since we were just talking about hiking boots (we know, it's a weird topic for a flip-flop article…bear with us), let's start there. If you love to hike on rugged trails, or often find yourself carrying a 20-pound pack on overnight backpacking trips, you obviously need to purchase a supportive and stable hiking boot. This will help keep your ankles from rolling, protect your toes from sharp rocks, and keep your joints healthy over the long-haul. Even if you're an avid hiker you likely aren't wearing your boots every day (outside of dedicated backpacking trips, of course). But think about how many hours per week you wear your flip-flops throughout the summer months. If you're anything like our testers, it could be every single day for extended hours each day! Obviously, flip-flops are not the right footwear for hiking miles of rugged trail or carrying a heavy pack, but even on mild terrain, it's still important to seek as much support and stability as you can out of your footwear, especially if you wear your open-toed footwear as much as we do.

Sandals with contoured footbeds are supportive enough to wear all day without pain or injury and stable enough to handle rocky terrain.

Sandals with contoured footbeds promote proper bone and joint alignment, keeping your feet and entire body healthier and happier. Thanks to their supportive footbeds, we comfortably wore models like the Gizeh and Ohana all day long without any discomfort. Likewise, we went on multi-mile hikes (over moderate terrain) in our Top Pick for Hiking and Scrambling, the Merrell Around Town. If you want a flip that you'll be able to wear all day - whether you're shopping beach-side boutiques or headed out on a mellow jungle trek - you should make the investment in a sandal with a contoured footbed

Fit


Finally, let's talk about fitting a pair of flip-flops properly. The first thing to remember is that this type of footwear tends only to be sold in whole sizes. Our main tester was a half size, so each review contains helpful information about whether sizing up or down is recommended.

Typically, when consumers first put on a pair of thong-style sandals at the store, they forget that as we start to walk, out foot slides forward until the area between the first and second toe is fully pressing against the toe post. Although it may seem subtle, the 1/16 or 1/8 of an inch that your toes may slide forward can completely alter the fit of a flip-flop. It's important to start here because this is how the sandal will fit when you are walking.

The placement of the toe post and the fit of the straps will both affect how far up your foot slides (i.e. looser straps will allow your foot to slide farther forward). Even though an specific model may seem like it fits the length of your foot while you're just standing, the fit may be slightly off once your toes slide up against the toe post. If any part of your foot is hanging off the sandal, steer clear and look for something that has tighter straps, adjustable straps, or a longer broader toe box.

Every flip-flop design will have slight differences in how the toe post feels  how wide and long the toe box is  and where the arch supports (if there are any) will fall. While we know shopping online is convenient and often more cost-effective  the more models you can try on in person the better your final fit will be.

While we know shopping online is convenient and often more cost-effective, the more models you can try on in person the better your final fit will be.

Once you've made sure that the toe post is well-placed and the straps fit the volume of your foot, tune into your arches. Make sure that you can feel some support under them, as this will help prevent conditions like plantar fasciitis. Different models have different arch heights, so choose one that feels natural under your foot. Some pieces like the Gizeh even have rounded heel cups that help keep the heel bone in place and provide extra stability. If this is the case with the model you're considering, be sure that your heel sits comfortably in the center of the cup.

If you have broader feet, products like the Ohana have wider soles and toe boxes.

The deep heel cup and strategic contouring of the Birkenstock footbed helps provide superior stability and support.

Lastly, think about strap fit. Different strap configurations not only affect the look and style of your sandal, but they are also an essential component of the overall fit. The classic V-shaped straps are seen on models like the Rainbow Single Layer Premier or Chaco Flip can be sufficient, but very often they will be too loose or too tight depending on your foot. For casual jaunts around town this isn't a big deal, but for longer days and more intense activities, it can be a deal-breaker.

Models like the Teva Olowahu have straps that crisscross over the top of the foot which can provide a tighter fit for some, but they also run the risk of being uncomfortable or unpractical for certain foot shapes. More stable and supportive models like the Birkenstock Gizeh or Merrell Around Town have buckles on the straps for adjustments, allowing more people to be able to get a perfect fit. This is a huge bonus if you have low-volume feet and tend to have difficulty finding straps that feel secure.

The take home point with all of this is that even minimal shoes like flip-flops have a lot of components to consider before purchasing - particularly if you plan to spend the majority of your time in them. Do your feet and body the favor of taking a little extra time to consider all of these features and your warm weather months can be even more enjoyable.
