The Scarpa Instinct VS combines a stiff forefoot and Vibram XS Edge rubber to deliver exceptional precision on small edges and granite crystals, while its split-sole design enables effective toe-hooking and tension on steep overhangs. OutdoorGearLab found this versatile architecture makes the shoe suitable for both vertical face climbing and boulder problems, though Climbingzine noted that the rigid sole construction significantly reduces sensitivity for smearing on slabs or reading subtle textures. The synthetic upper materials ensure minimal stretch but require a lengthy break-in period before comfort is achieved, and the relatively high-volume toe box makes crack climbing and thin jams difficult and uncomfortable. This performance shoe fits climbers with medium to wide feet seeking precision on steep terrain, while those prioritizing slab sensitivity or traditional crack climbing should look elsewhere.

Strengths
  • — Stiff forefoot and Vibram XS Edge rubber provide exceptional precision on small edges and granite crystals.
  • — Split-sole design with a flexible midfoot allows for effective toe-hooking, heel-hooking, and tension on steep overhangs.
  • — Bi-Tension arch support system distributes weight away from the toes, offering comfort despite the aggressive fit.
Watch-outs
  • — The rigid sole construction significantly reduces sensitivity for smearing on slabs or reading subtle textures.
  • — Tight synthetic uppers require a lengthy break-in period before the shoe becomes comfortable to wear.
  • — The relatively high-volume toe box makes crack climbing and thin jams difficult and uncomfortable.
Tenaya Mastia
Ranked #5 in Best Climbing Shoes
Tenaya Mastia
2 sources$194.72as of Oct 11

OutdoorGearLab found that the Tenaya Mastia offers a comfortable alternative to typical high-performance climbing shoes thanks to its soft uppers that conform well to the foot. Climbingshoereview highlighted the shoe's asymmetric shape and stiff forefoot, which provide incredible support on small edges while maintaining sensitivity for smearing. While reviewers praised its versatility across sport climbing and bouldering, some noted it lacks the ultimate precision of specialized models on vertical walls or artificial holds. This shoe is best suited for climbers seeking a comfortable, high-volume fit with strong edging capabilities rather than those prioritizing maximum sensitivity.

Strengths
  • — Highly asymmetric design with a stiff forefoot provides exceptional power transfer and confidence on tiny edges and technical holds.
  • — Superior heel cup construction featuring dual rubber runners that deliver secure grip during aggressive heel hooks and pulls.
  • — Versatile performance balance, effectively bridging the gap between edging support for vertical terrain and sensitivity for smearing.
Watch-outs
  • — Requires significant downsizing (up to two full sizes) from street shoe size due to minimal synthetic stretch in the upper material.
  • — Lacks precision and sensitivity on slippery artificial gym holds compared to specialized, ultra-sensitive bouldering shoes.

How they stack up

Scarpa Instinct VS

The Scarpa Instinct VS uses Vibram XS Edge rubber like the La Sportiva Katana Lace, but in a split-sole Velcro design with a flexible midfoot rather than a stiff lace-up. Its relatively high-volume toe box makes thin jams difficult, so the flat La Sportiva TC Pro is the better fit for crack climbing.

Tenaya Mastia

The Tenaya Mastia offers outstanding comfort and a slipper-like fit due to its unlined microfiber uppers, making it more comfortable for long sessions than the tight-fitting La Sportiva Solution Comp. Its stiff forefoot provides exceptional power transfer on tiny edges.
