How to Measure Your Foot for Climbing Shoes
Follow these steps for accurate measurement:
- Measure your feet in the evening when they’re naturally swollen
- Stand on a piece of paper against a wall
- Mark the longest toe and heel points
- Measure the distance in centimeters or inches
- Measure both feet as they may differ slightly
- Use the larger measurement for sizing
Understanding Climbing Shoe Sizing
Climbing shoe sizing differs significantly from regular footwear. Most climbers wear shoes 1-2 sizes smaller than their street shoe size. This tight fit provides better sensitivity and precision on small holds.
The perfect climbing shoe should feel snug but not painfully tight. Your toes should be slightly curved but not painfully cramped. Remember, leather shoes will stretch over time, while synthetic materials maintain their shape.
Key Factors for Choosing Climbing Shoe Size
- Climbing experience: Beginners should choose less aggressive, more comfortable fits
- Foot shape: Consider your foot width, arch height, and toe length
- Climbing style: Different disciplines require different fits and features
- Material: Leather stretches more than synthetic materials
- Brand variation: Each manufacturer has unique sizing standards
Different Climbing Styles and Shoe Requirements
Sport and Gym Climbing: Moderate downturns work well. Comfort matters for longer routes. Choose shoes you can wear for extended periods without significant pain.
Bouldering: Aggressive downturns excel on overhangs. Tighter fits provide maximum precision on small holds. Prioritize performance over long-term comfort.
Traditional Climbing: All-day comfort is crucial. Moderate fits prevent foot fatigue on long multi-pitch routes. Consider crack-specific features for jamming.
Multi-pitch Climbing: Comfort becomes paramount on long routes. Choose shoes that won’t cause hotspots or numbness during extended wear.
International Size Conversion Considerations
Size conversions between US, UK, and EU systems aren’t always exact. Each climbing shoe brand may interpret these conversions differently. Always try shoes on when possible, or consult brand-specific size charts.
Women’s climbing shoes typically run 1.5-2 sizes larger than men’s in US sizing. EU sizing is generally unisex, making it more consistent across genders.
Breaking in Your Climbing Shoes
- Leather shoes: Will stretch 0.5-1 full size with use
- Synthetic shoes: Minimal stretching, buy the size you need
- Lined shoes: Less stretching than unlined versions
- Heat molding: Some brands offer custom molding services
New climbing shoes should feel tight but not unbearable. If you experience sharp pain or numbness, the shoes are too small. Gradual break-in periods help feet adapt to the tighter fit.
Common Sizing Mistakes to Avoid
Many climbers make the mistake of sizing too aggressively. Overly tight shoes can cause injuries, reduce climbing time, and actually decrease performance due to discomfort.
Don’t assume your size is consistent between brands. La Sportiva, Scarpa, Black Diamond, and other manufacturers all have unique lasts and sizing philosophies.
When to Replace Your Climbing Shoes
- Worn-through toe rubber affecting performance
- Sole separation from upper materials
- Significant stretching that reduces precision
- Persistent odor that cleaning can’t eliminate
- Your climbing style or foot shape has changed
Quality climbing shoes can be resoled multiple times, extending their lifespan significantly. Professional resoling costs much less than new shoes and maintains the broken-in fit you’ve developed.
Remember, the best climbing shoe size balances performance with comfort for your specific climbing goals. Use this calculator as a starting point, but always prioritize how the shoes actually feel on your feet.

FAQs about Climbing Shoe Size Calculator
How do I convert climbing shoe sizes between systems?
Our calculator automatically converts between US, UK, EU and Japanese sizes based on your current shoe size.
Should climbing shoes fit tight?
Fit depends on climbing style – comfort fit for beginners, performance for intermediates, aggressive for advanced climbers.
Why do climbing shoe sizes vary by brand?
Each brand uses different lasts (shoe molds) and materials that stretch differently, causing size variations.
How much do leather climbing shoes stretch?
Leather shoes typically stretch half to a full size, while synthetic shoes stretch minimally (about 0.5 size).
When should I replace climbing shoes?
Replace when you see holes in the toe, lose sensitivity, or the rubber no longer grips well (typically 6-12 months with regular use).
