Climbing Shoe Sizing: The Honest Guide (From Someone Who Deals With This Daily)
Climbing Shoe Sizing: The Honest Guide (From Someone Who Deals With This Daily)
Getting climbing shoe sizing right is one of the trickiest parts of buying gear — and honestly, one of the most misunderstood. If you’ve ever tried on multiple brands and thought “how am I three different sizes?”… you’re not alone.
I deal with this every day, and the reality is: there is no universal sizing in climbing shoes. Each brand fits differently, and some break the “rules” completely.
Let me walk you through it properly — especially for Evolv, Unparallel, and EB — as these are the ones that tend to cause the most confusion.
The Big Myth: “You Should Always Size Down”
You’ll hear this everywhere — “climbing shoes should be smaller than your street shoes.”
That’s often true for brands like Scarpa or La Sportiva…
…but it’s not a universal rule.
In fact, with some brands (especially Evolv), doing this will absolutely wreck your feet and give you the wrong fit.
Evolv: The Exception to the Rule
This is the one I always flag to customers.
If you’ve worn Evolv before, you’ll know your size.
If not… expect it to feel completely backwards.
Key point:
👉 Evolv usually requires sizing UP, not down.
From experience (and what I tell customers):
- Go +0.5 to +1 size above your normal trainers
- Performance models run tighter and more aggressive
My own example:
- Trainers: 9.5
- Evolv (Shaman, Zenist, Kronos): 10.5 for performance fit
- That’s a full size up — and that’s completely normal
Why?
- Evolv builds shoes with a tighter internal volume and aggressive shaping
- The sizing scale simply runs smaller compared to other brands
Quick takeaway:
If Evolv feels brutally tight at your normal size — you’re probably in the wrong size, not the wrong shoe.
Unparallel: The Stealth Fit (Close to Five Ten Feel)
Unparallel is a bit more familiar if you’ve ever worn older Five Ten models.
General rule:
- Start at true to size (your normal trainers)
- Adjust slightly depending on how aggressive you want the fit
Fit notes:
- Medium to slightly wider fit (good for UK climbers)
- Less extreme sizing swings compared to Evolv
- High-performance models (like Flagship/TN Pro) will feel tighter but still predictable
My advice:
- Want comfort → stick to your normal size
- Want performance → go half a size down at most
EB: The Underrated Middle Ground
EB tends to sit somewhere between comfort and performance.
They don’t get talked about as much, but sizing is actually more forgiving and consistent.
General rule:
- Start at true to size
- Go half size down if you want a tighter performance fit
Fit notes:
- Good for beginners through to intermediate climbers
- Slightly more comfort-focused out of the box
- Less aggressive downturn compared to Evolv
Why Sizing Feels So Inconsistent
It’s not just you — brands genuinely build shoes differently:
- Last shape (foot mould) varies massively
- Rubber tension systems affect how tight shoes feel
- Upper materials stretch differently (synthetic vs leather)
- Intended use (comfort vs performance) changes sizing expectations
That’s why you can be:
- 10.5 in Evolv
- 9.5 in Unparallel
- 8.5 in Scarpa
…and all of them fit “correctly.”
The Practical Way to Get It Right
Here’s what I usually recommend to customers:
- If you know the brand → stick with what works
- If you’re switching brands → don’t assume sizing carries over
-
Start from your trainer size and adjust:
- Evolv → go UP
- Unparallel → stay true
- EB → true or slightly down
And most importantly:
👉 Fit matters more than the number on the box
A “perfect” climbing shoe should feel:
- Snug everywhere
- No dead space
- Toes slightly curled (but not painful)
- Secure heel
Not:
- Numb
- Crushing
- Impossible to stand in
Final Thought (The Bit I Always Tell Customers)
Climbing shoes are tools — not a badge of honour for how much pain you can tolerate.
If you get the sizing right:
- You’ll climb better
- Your feet will last longer
- And you won’t dread putting them on
If you’re unsure, I’m always happy to help dial it in — it’s genuinely one of the most important decisions you’ll make when choosing shoes.
