How Should Climbing Shoes Fit? A Guide for New Climbers

Finding the perfect climbing shoe fit can be confusing, especially when you’re just starting out. Too loose and you’ll lose power and precision. Too tight and every move will feel like torture. So how should climbing shoes actually fit — and how do you avoid common mistakes when buying your first pair? Read on to learn what to look for and how to make the best choice.

Whether you’re shopping in-store or online, understanding climbing shoe fit will make a huge difference in your comfort and performance.

What Does a Good Fit Feel Like?

Climbing shoes should feel snug — much snugger than your everyday sneakers — but not painfully tight. Expect your toes to be slightly curled (especially in aggressive models) and your heel to be locked in with no air pockets.

You want the shoe to feel like a second skin: no bunching, no dead space, and no major pressure points. The tighter fit allows for better precision on footholds, but if it crosses the line into pain or numbness, you’ll struggle to climb well or at all.

Common Fit Mistakes to Avoid

Fit can be tricky, especially if you’re new to the sport or buying online. Here are a few pitfalls to watch for:

• Sizing down too aggressively: A tighter fit can improve performance, but if your shoes are causing sharp pain, numbness, or bruising, they’re too small. You shouldn't dread putting them on.
• Leaving too much space: A loose heel or roomy toe box means your foot will slide inside the shoe — leading to poor precision and wasted power.
• Not considering foot shape: If you have narrow feet, a regular-volume shoe might leave gaps. Consider low-volume (LV) models instead. Read our guide on LV vs regular climbing shoes.
• Buying without trying them on: Even shoes in the same size vary greatly between brands and models. Always try them in person if possible — or order from a store with a good return policy.

Key Fit Factors to Watch Out For

Not all climbing shoes are made equal — and certain design elements will impact how they feel on your feet.

• Toe box shape: Some shoes have a more pointed toe box (great for pockets and precise edging), while others are rounder for comfort. Make sure your toes fill the space without curling uncomfortably.
• Shoe volume: Volume refers to the overall internal space. Climbers with low-profile feet may find a better fit in LV (low volume) versions. Learn more about LV vs regular shoes here.
• Closure system: Lace-ups allow fine-tuned adjustment, Velcro straps offer convenience, and slippers are quick to slip on and off. Each closure affects how snugly the shoe wraps around your foot.
• Material stretch: Leather shoes tend to stretch more than synthetic ones. If you’re buying leather, expect them to loosen up over time — and factor that into your sizing.

Should Climbing Shoes Hurt?

This is one of the most common questions from beginners — and one of the most misunderstood. The short answer: no, they shouldn’t hurt.

A well-fitting shoe should feel tight, yes — but not so much that it causes pain or limits your movement. Slight discomfort is normal at first, especially for aggressive models, but pain is not a sign of better performance.

Here are a few tips for managing discomfort without overdoing it:

• Choose shoes with a moderate profile and soft materials for your first pair.
• Break them in gradually. Wear them around the house or on easier climbs to allow your foot to adjust.
• If the shoes cause lasting pain or bruising, try a different size or model.

Try Before You Buy: Tips for Fitting in Store

Whenever possible, try climbing shoes in person. Here’s how to make the most of it:

• Bring your climbing socks, if you plan to wear any. Most climbers go barefoot, but it’s up to you.
• Test for performance: Scrunch your toes, stand on your tiptoes, simulate a heel hook, or try edging on a wall or simulator if available.
• Try multiple models and sizes: Even within the same brand, fit can vary. Don’t settle too quickly.
• Ask for advice: Our staff at Boulder Planet Showroom know their shoes and are happy to help you find the best fit.
