Climbing shoes are typically worn smaller than street shoes. For trad and moderate shoes, size down 1–2 sizes. For aggressive shoes and slippers, La Sportiva recommends sizing down 2–3 sizes from your street shoe size. Keep in mind that unlined shoes stretch about one full size with break-in; lined shoes stretch about half a size.

How it works
The La Sportiva Tarantulace is the best-selling climbing shoe in the US — and for good reason. Climb harder and longer while suffering less, thanks to an unlined leather upper, asymmetric shape, and roomier toe box. FriXion® RS rubber is sticky yet hard-wearing for an increased durability and a powerful edging platform, while an aggressive rubber heel rand keeps you glued to small holds. The ideal one-quiver shoe for outdoor and gym climbers who need versatility, durability, comfort, and affordability all in one.
Features
- FriXion® RS rubber outsole — ultra-sticky compound for maximum grip with long-term durability
- Aggressive rubber heel rand for secure purchase on small holds
- Quick-pull lacing harness delivers precise fit regulation and snug, supportive wrap
- Unlined leather upper with asymmetric shape and roomier toe box for comfort on long sessions
- Lined tongue for moisture management
- 1.8mm LaspoFlex midsole balances sensitivity and support
