Athletic Performance Insoles — Protalus Landing Gear
Protalus Landing Gear — Sports Performance
Every field is flat. Your foot wasn't built for that.
Flat surfaces cost 2–3% running economy every step — a debt that compounds across a full game. Landing Gear restores the joint geometry your sport needs, closing the gap from the first step.

Of mechanical energy should come from elastic return. Flat ground prevents it from firing.

Correct joint range in M-100 vs. 0 of 31 on standard foam — independent 3D motion capture.

The mechanism
Every move you make starts from the ground up.
Bat speed. First step quickness. Shot power. Change of direction. All of it originates from ground reaction force transmitted through the same chain. Break that chain at its base — the subtalar joint — and every link above it works harder than it should to compensate. Thousands of times a game.

Output
Pronation at heel strike stores elastic energy in the plantar fascia, Achilles, and intrinsic muscles. Supination at push-off releases that energy like a spring — but only if the heel lands on the correct oblique axis first. A flat field, court, or track can't send that signal. Disrupt the axis loading and you don't just lose some efficiency — you lose the mechanism entirely.
Landing in slight supination on the correct geometry is like pulling back a bow. On flat turf the bow is never drawn — every push-off is a release with nothing behind it. That's not a technique problem. That's geometry.

Superman has Kryptonite. You have Landing Gear.
Every athlete on that field is competing on the wrong surface. Most of them always will. Your body was built for different ground. Now you can give it back.
