How tight should climbing shoes be?

Snug with no dead space — toes should be slightly curled but not painfully cramped. Beginner shoes should be comfortable-snug; you'll wear them for hours. Performance shoes for experienced climbers are tighter for precision. Leather shoes stretch 0.5-1 size; synthetic shoes barely stretch.

Should I size down in climbing shoes?

Beginners: go true to size or half size down. Intermediate: 0.5-1.5 sizes down depending on shoe style. Aggressive shoes require more downsizing than flat shoes. Always try before buying — sizes vary wildly between brands.

When should I resole climbing shoes?

Resole when rubber gets thin but before you wear through to the rand (the rubber wrapping the shoe). A resole costs $35-55 and is worth it for shoes over $100. Once the rand is damaged, resoling is more expensive and less effective. Check sole thickness monthly.

The "Size Down Until It Hurts" Myth

Leather-lined shoes stretch a full size. Synthetic shoes stretch barely a quarter. Lined leather is in between. The correct fit depends on level and construction.

Right Fit By Level

Beginner: snug, mild pressure, slight toe curl, wearable 30+ min. Intermediate: tighter, toes curled, some discomfort. Advanced: performance fit for sends, camp shoes for belaying.

Shoe Shape Matters More Than Size

Foot shape (Egyptian, Greek, Roman) should match toe profile. Egyptian foot (big toe longest) → La Sportiva. Greek foot (2nd toe longest) → Scarpa. Mismatch creates pressure points no break-in fixes.
