Styles of Climbing Shoes
What Type of Climbing Will You Be Doing?
Do you live in Florida, and anticipate only using using these shoes in the gym for the foreseeable future? Are you moving into Camp 4 for the summer and plan to live off Chef Boyardee and Coors Lite so you can climb full-time? You want shoes for the type (or types) of climbing you're going to be doing, and you want them to be sized appropriately.
Bouldering and Sport Climbing
Trad and Crack Climbing
Gym Climbing and Starting Out
For gym climbing, get whatever suits your climbing ambitions. Tight and aggressive for really getting after it, or a flatter, looser fit if you're new to climbing, cruising, or just getting some exercise.
There is a lot of subjective information out there regarding how you should size your shoes. For sport climbing and bouldering there is a pretty strong correlation between the difficulty of the climb and your shoe size: as the number grade of the climb increases, the number of your shoe size decreases correspondingly. This inverse relationship is due to the simple fact that tighter shoes perform better. However, there is a limit to an increase in tightness increasing performance. If your feet hurt so much that you don't want to, or can't climb, you've gone too far. Tight shoes also work for sport climbs and bouldering because you tend not to be on the rock for very long.
On multi-pitch climbs, whether sport or trad, you'll want to size your shoes more loosely. Particularly for trad climbing, having a flatter-toed shoe that is a little larger will benefit you when climbing cracks. You can compensate for a slightly larger size by choosing a shoe with a stiffer sole. Even on longer multi-pitch sport climbs, a less aggressive shape (less down-turned, lower asymmetry) will keep your feet from getting thrashed, with a fairly minimal diminishment in performance.
Again, doing some research will go a long way for you. Before you buy, decide what type of climbing you'll mostly be doing with the shoe, and size them accordingly. A few things to consider: unlined shoes stretch more over the lifetime of the shoe, and can lose performance. Half sizes matter, particularly in climbing shoes. A slightly larger shoe won't impact your climbing very much at all, and can make a world of difference in terms of comfort.
Down-turned toes are everywhere these days. The more down-turned a shoe, the more your toes bunch up in the front. Sizing down-turned shoes loosely will mean that you have extra material on top of your foot where your arched toes should be. When you climb in an over-sized shoe, that excess material can bunch up, both getting in the way and making the shoe less comfortable. If you're in the market for down-turned shoes, remember to keep them snug. That doesn't mean they have to hurt, but they should be tight enough to perform for you.
The shoe that you take out of the box the first day you climb with it will not be the same after wearing it for a while. All shoes stretch, some more than others, so it is important to size your shoes to account for how they will feel after wearing in.
Leather shoes stretch more than synthetic shoes, so take that into account when making a purchase. However, leather shoes that are lined stretch very little, but will mold themselves to your feet to some extent. How much do you size leather shoes down to accommodate for stretch? That depends a lot on the brand and model, and there will be a little trial and error here. In general, to get the right fit from your unlined leather shoe, size them a little tighter, and expect them to be mildly uncomfortable, with the discomfort decreasing as they wear in. The end result should produce a comfortable shoe. Synthetic shoes don't stretch out much at all, so make sure they are fairly true to size when you buy.
Gathering a little information on the shoe you are going to buy will help you make this decision. What does the manufacturer say about the shoe? What materials were used to construct the shoe? What is the design of the shoe? For example: a lot of shoes feature rubber on top of the toe for hooking, which prevents the shoe from stretching as much. These are all good questions to ask, and will help guarantee you stay stoked with your decision.
Brand and Sizing
Go out and try on various brands and sizes before you buy, if you can. Evolv and Five Ten both run small, now making it possible to size your rock shoes the same as your street shoes. La Sportiva and Scarpa are very consistent, but require a little figuring to learn what their sizing means. For us, it means we buy these European brands one size down from our street shoe size.
Laces, Velcro, and Slipper
There are three main types of tightening system: Velcro strap(s), lace-ups, and slippers (usually elastic). Lace-up shoes are the most adjustable, and typically provide the most uniform, customizable fit for your rock shoes. All those strings make them a little slower to put on and take off. Because of this, we tend to choose lace-ups as all-around/multi-pitch shoes, where we put them on at the start of the climb, and take them off at the end. Velcro shoes go on and off easier, and some tighten almost as well as lace-ups. For sport, bouldering, or gym climbing, velcro shoes are great because of the number of transitions between street shoes and rock shoes that you make in a day. They work well on multi-pitch days too, if you want to pop the velcro for a little relief at the belay. Slippers are usually the most sensitive and comfortable shoes out there. They are usually unlined, which means they stretch out more. This makes them more comfortable, but also decreases their performance. They are very easy to take off, and make great gym or bouldering shoes.
Laces wear out, get torn up by cracks, and get turned into rappel anchors (don't really do that). Just be ready to replace them when they start to look worked. Velcro will get mucked up if you leave it open when you're storing the shoes. Keeping the velcro closed when you're not using your shoes will also help keep the shape of the shoe longer. Tip: your friend's toothbrush (or the one you use to clean holds) can be used to brush out the velcro if it's starting to look gummy.
Difference in rubber preference stratifies opinion more than any other aspect of climbing. As a rule, rubber that is stickier is usually softer and less durable, and less sticky rubber is typically harder and more durable. Really soft rubber that is ultra-sticky will wear out fast. It also gets pocked or fish-scaled quickly, and tends to slide off edges. Harder rubber holds an edge longer, but doesn't function as well when you paste your foot on the rock. Consequently, we tend to use the different rubber types for different applications. Softer rubber for high performance sport and bouldering shoes will typically work better for everything other than steep edges. When just starting out as a climber, or if you're looking for an all day shoe, harder, more durable rubber will work better.
