Rock climbing is only possible to do well when you have a shoe that fits your foot. Climbing shoe size ranges are often smaller than what is available for other footwear like running shoes. In this post we break down all the shoe companies and what sizes they offer.

What is the largest size climbing shoe?

The largest and biggest adult size climbing shoe is US Men’s 17 (EU 52) from Red Chili – with the models Red Chili Sausalito and Red Chili Session (a rental shoe).

Brands that make US M 16 / (EU 52) shoes are:

  • Butora
  • Evolv
  • Red Chili
  • Saltic

Brands that make a US M 15 (EU 50) shoes are:

The next smallest shoes are by Wild Climb who has many models of shoes starting at US M 2 (EU 33) and even more shoes starting at US M 2.5 (EU 34).

Climbing Shoe Size Charts

Most US size charts are still based on a traditional gender model, even if a company uses high/low volume language. When you look at the size chart for a low volume shoe, you’ll see a Women’s size chart or sometimes a size chart that includes both Men’s and Women’s sizing. The EU and UK make it much easier to find your size, no matter the volume of your foot, as there is only one comprehensive size chart and it is not split in gender.

That said, although a number of companies are moving away from gender and towards more descriptive high/low or regular/wide volume terminology, the size runs have not always caught up to this change. According to Healthline, the average US Men’s shoe size is a 10.5 yet women’s shoes still tend to top out around a size US W 10 (EU 42) which is only a Men’s 8.5 (EU 41.5).

Note: WeighMyRack lists the brand size chart along with the specs of each shoe model.

For consistency, we’re listing sizes in US M and EU. We’re using US M because that’s how most manufacturers list shoes and it is what is used when a unisex range is presented.

A Note on Gender in Climbing Shoes

Most seasoned climbers know that although there are “men” and “women” labels on shoes, if you have a high volume foot, no matter your gender, it’s likely a men’s shoe will fit better because the lasts used to make men’s shoes are larger in volume. If you have a lower volume foot it is likely a women’s shoe will fit better for the opposite reason.

Similarly, there are a few companies, such as SCARPA and La Sportiva, who change the type of rubber on the men’s versus women’s shoe. The women’s shoe can have a stickier/softer rubber for lighter climbers and then men’s shoe has a harder rubber that will not deform as much with a heavier weight. Or the thickness of the midsole might change between the men’s and women’s model, providing a stiffer, thicker midsole for the presumed heavier male climber. Again, this is by design as studies (including Gallup) continue to show that on average women are about 19% lighter than men. To me this says companies aren’t looking just to “shrink it and pink it” and are going further into the nuances of design between models.

Perhaps in the future these shoes will be labeled “soft” or “hard” in addition to low/high volume. Or the “soft” shoes will come in smaller sizes while the “hard” shoes are reserved for larger feet which typically follow a larger height.

Previously we’ve heard shoe companies state that they’d like to move more towards high/low volume language but they’ve had pushback from the retailers. From a retail perspective, gendered shoes are helpful because it allows the retailers to merchandise products easier and they believe it’s easier for a customer to better find their shoe, by starting with gender.

The Future ?!?

One brand we talked to dreamed of not only choosing between a high/low volume shoe with a soft/hard option, but also being able to choose a shoe that had options for a “small” or “normal” heel.

Even if each brand doesn’t make every model of shoe in 6+ variations, it’d be great to see each brand list all the foot fitting details, like instep (high/low), toe type (Egyption, Greek, Roman), toebox width (wide/narrow), toe length (short/long), heel hight (short/long), and heel width (wide/narrow).

Currently it’s rare for shoe companies to list which foot configurations fit best, but this could (should!) be the next trend we see in helping to get a proper fit. Ocùn and Red Chili have nice graphics in this direction.

This post is sponsored by REI as part of a Size Inclusivity in Climbing series. In 2021 REI made an announcement that they were making a “commitment to becoming a fully inclusive, anti-racist, multicultural organization.” They followed this announcement with the Product Impact Standards, a document that specifically outlines the requirements that any partner brands they work with must meet.

By Spring of 2024, REI is requiring all apparel/gear partners to include marketing diversity and inclusive sizing as defined by these standards:

  • …have in place inclusive guidelines for marketing assets, photo casting and production that ensure diverse and inclusive representation across race, age gender identity/expression, body size/type and disability.
  • …each brand partner that sells wearable products offered in a variety of sizes to provide REI at least one sample size outside the standard size range for marketing photography.
  • …expects that all wearable products offered in a variety of sizes maintain the same price within a style regardless of size.

By Spring of 2025, they’re requiring a diverse hair type inclusion standard:

  • …each brand partner that produces headwear (helmets, hats, headbands, hoods, balaclavas, hijab, etc) to have in place guidelines for ensuring an inclusive assortment for a variety of hair types, including higher-volume and textured hair.

If you’d like to read more about how REI is fighting climate change, advancing inclusion in the outdoors, and managing chemicals, the Product Impact Standards are a great way to learn more.

Our Best Advice for Climbing Shoes

Go to shoe demos (at the gym or climbing festivals) and try on ALL THE SHOES. Including the high and low volume versions of the same model. Ideally, try climbing the same routes in each pair so you can get a sense of how they fit and perform differently. Note how they fit: are there pressure points or any gaps between your foot and the sides / top / bottom of the shoe? Pick what fits snugly and feels right to you.

If there’s a spot on a shoe that’s nagging you or any part of your foot slips in the shoe, keep trying on shoes. After trying on a ton of shoes, at one point you may wonder, “is this shoe perfect?!” because you can’t find anything wrong with the fit – at this point trust your intuition. And, for future reference, write all this info down on your phone: whether the shoe model fit or not, and what sizes are good/bad.
