The Tide II is at first glance an unassuming sandal that, test after test, showed us what a well-constructed flip-flop should offer. While the very prominent arch support won't be for everyone, those that prefer a heavily contoured footbed will likely find this shoe quite dreamy. It was at the top of the pack for support, stability, durability, traction, and more. The Birkenstock Gizeh and Astral Rosa landed just above the Tide II, but it was a close race.
This is an impressive flip flop all around that we really enjoyed wearing.
The Tide II has a particular kind of comfort that some people either won't like or will need time to adapt to. The footbed has orthotics built into it, giving it intense arches that could cause pain for people with flat feet. Even our main tester, who had naturally high arches, felt some discomfort and cramping at times.
The shape isn't for everyone, but for those that love full arch support, there was no better model in our test group. Partner that with a pleasantly textured footbed and foam-lined straps and you have an excellent package.
The intensely contoured footbed of the Tide II has the potential to be really comfortable if you happen to like high and pronounced arch support.
For comfort that is more readily accessible and less aggressive, the OluKai Ohana was our most comfortable shoe, though it didn't provide quite the same level of support. This may have been a sizing issue though, discussed in more detail in the next metric, support, and stability. The sandal that we felt balanced comfort and security the best was our Editors' Choice, the Birkenstock Gizeh.
Support & Stability
We found the Tide II to have some of the best support of any of our tested models. Only the Gizeh with its ergonomic footbed and the Astral Rosa with its add-on ankle straps scored higher.
We feel it's only fair to mention that the Tide II was able to score so well in this category primarily because we changed the size. Our chief tester was a size 8.5, so we ordered 9's for almost all of our sandals. But the size 9 Tide II was so large it almost looked like a random men's shoe had been thrown in with our women's models! We returned it and opted for a size eight instead which was a smart choice. It put the arch in the proper place and gave us a snug fit. For comparison, the Ohana also ran a ran a bit large, but not enough to warrant an exchange. This affected how stable and supportive it felt and, ultimately, its score for this metric. Even with minimal footwear like flip-flops, proper sizing is crucial. We recommend trying things on in person whenever you can, or at least obtaining a footbed measurement from the manufacturer or another reputable source.
Once we figured out our perfect size, the Tide II was an impressively stable and supportive flip. They seem to run quite large, so if you have a half size foot you will want to size down.
Again the Tide II rose to the top of the pack. This is a well-constructed flip-flop that still looked brand new after several months of rigorous testing.
We have zero reservations in saying that this model will have no problem lasting you many years. We found nearly the same level of durability in the Chaco Flip EcoTread, though the sole isn't quite as thick or robust. The Astral Rosa was also an impressively durable model that still looked new after getting the full treatment from our testers.
The Tide II is among the most durable of all the flip flops we tested.
No surprise, the durable rubber, and webbing of the Tide II were also highly water resistant. When walking around with a wet footbed the shoe temporarily felt a little bit slippery and made farting noises, but the material is so nonporous that it was dry again extremely quickly.
After laying out in the sun, this drenched sandal had a dry footbed in four minutes flat. The straps took a full half hour to dry, but they felt fine to wear while damp. The Rainbow Single Layer Premier was the top performer in this category, drying thoroughly - straps and all - in just 20 minutes.
Some of our top performers in the water resistance test, from L to R: the Reef Leather Uptown, Olukai's Lala and Ohana, the Rainbow Premier, and the Vionic Tide II.
Once again, the Tide II outperformed almost all the other models we tested. Frankly, we were shocked at the level of traction we received from this simple flip-flop.
The treads were sticky and secure, and we felt great hiking up steep and chossy slopes. Since this shoe has relatively small straps, this level of security is contingent on having the proper fit and, as explained above, we had to size down to achieve that.
Outfitted in the Tide II we were able to confidently get up uneven and unpredictable terrain, even with a heavy pack.
The only model that provided better traction was the rugged Merrell Around Town. With impressive treads and wide adjustable straps, we felt almost as secure as having fully enclosed hiking shoes on. The Gizeh, our Editors' Choice, was also a top contender, with the best internal footbed traction of the group, as was the Astral Rosa with its supplemental ankle straps.
Some of our top performers for traction, from L to R: the Birkenstock Gizeh, Vionic Tide II (middle), and Merrell Around Town Thong Buckle. Setting these shoes on a slick and angled wooded box was revealing.
Style is the one category where the Tide II didn't measure up to the rest of the pack. The thick soles and relatively drab design weren't super appealing to most of the women we polled.
Vionic does offer similar models that have patterned straps, rhinestone or sequin bejeweled straps, and even a version with a wedge heel, but these still retain a relatively sporty and clunky look that can't measure up to more fashionable designs like the OluKai Lala, our Top Pick for Stylish Adventures or the Birkenstock Gizeh.
Some women like the look of the Tide II, but compared to the rest of our test suite it wasn't a style favorite.
The great thing about this flip-flop is that it's well suited for almost any kind of situation. Need amazing traction? Check. Impressive arch support and stability? Done. Want to play around in the river and be dry again quickly? No problem. From a simple walk to dinner or a tenuous hike to the crag, this super durable sandal has you covered from practically every angle. It's maybe not the shoe you'll grab when you want to get dressed up, but for every other aspect of a fun and activity-filled summer, it will treat you well. Do be aware that the arch supports from built-in orthotics are aggressive, so it's also not the model to pick if you prefer a flatter footbed.
The Tide II retails for $65, smack in the middle of all our tested flips. It's a bit of an investment, but not so much as to break the bank — and we think it's well worth the price tag. Durable and well-constructed with amazing support, this sandal will have no problem lasting you for many years.
Overall we found the Tide II to be a highly impressive piece of footwear. It performed at the top of the pack in almost every rating metric, just barely falling short of nabbing first place. Traction, stability, durability, water resistance — this flip-flop almost has it all. It isn't as plush or soft as other models, and its sporty look fell a bit short of its competitors in the style department, but this is a sandal we would highly recommend for anyone with an active lifestyle looking for superior arch support.
The Tide II is one of the more secure and supportive options in our test suite.
