Fast Insole

When your stock insole isn't keeping up on technical terrain, the Fast Trail is a straightforward drop-in upgrade for any trail shoe. Dual-density construction pairs a firm heel cup with softer foam on top — locking your foot in place while still delivering quick, responsive rebound. Fits a wide size range, so it works across most shoes we carry.

• Dual-density build combines a firm heel base with softer foam on top for support and cushion in one package
• Firm heel cup stabilizes your foot on technical terrain and reduces fatigue over long miles
• Lightweight foam layer delivers quick rebound without adding bulk or dead weight underfoot
• Unisex sizing runs XXS through XXL — fits a wide range of trail shoes, not just Oboz
• A direct replacement for worn-out stock insoles when the factory footbed stops performing
