Tenaya Mastia
Tenaya
Aggressively curved shoe from Tenaya's Aerial Plus line, designed to power through steep boulder problems and overhanging sport routes. Down-angled, low-profile toe box drives into shallow pockets and thin cracks. Split-sole construction with Vibram XS Grip 3.5mm rubber delivers targeted grip where it matters most. Unlined construction keeps weight down and sensitivity high.
