Protalus T-100 Landing Gear
The surface your body lands on. Thinner fit. Patented alignment in motion.
What they’re landing on is.
The ground is flat. Your body isn’t built for that. The Landing Gear from Protalus is the missing surface — the one that turns every heel strike into comfort instead of compensation.
Over 2,000,000 satisfied Customers
Your body was built for uneven terrain. Then the world went flat. Protalus is the landing surface that sidewalks, tile, and concrete never gave you.
Varied. Uneven. The foot knew what to do.
Flat on the left. Flat on the right. Your heel has nothing to work with.
The patented surface that puts the missing angle back under your heel.
Flat floors force your joints to absorb every step. Other insoles copy the shape of a foot at rest. Protalus patented the geometry of a foot in motion. A Landing Gear for your feet that affects your whole body.
The best place to start. Slips into almost any shoe you already own, and you'll feel the difference in your first few steps.
Everything the T-100 does, plus
anti-fatigue cushioning for hard floors, long shifts, or days when the ground just won't let up.
Maximum alignment correction, full-length support. Built for boots, work, hiking, or safety, with the depth to hold it right.

T-75 and M-75 sit on top of a fixed insole. H-75 is built for heels. Best for: dress shoes, tight fits, non-removable liners
Every surface punishes differently. Protalus is landing gear engineered for them all.
12-hour shifts on hospital tile. The floor never changes. Your landing gear handles the biomechanics so you can focus on the patient.
10+ miles a day on concrete. One of the world’s largest warehouse operators deployed Protalus for hundreds of thousands of workers. Now it’s your landing gear too.
Standing still is harder on your body than walking. Landing gear keeps the ankle loaded correctly even when stationary — reducing the venous pressure behind heavy, aching legs.
Safety boots protect your toes. They weren’t designed for 8 hours on concrete slab. Protalus landing gear fixes what the boot can’t — the geometry of your gait, every step.
The same geometry that protects warehouse workers makes runners efficient. When your drive shaft is on axis, energy recycles instead of dissipating.
Balance degradation is partly mechanical. Landing gear restores accurate proprioceptive feedback through the foot — improving balance on any surface, any terrain.
The number tells you the length of the insole. The T-100 and M-100 are full-length landing gear that extends to the end of your foot. The T-75 and M-75 are ¾-length — they stop at the ball of the foot but deliver identical geometry.
Absolutely. Protalus insoles are designed to transfer shoe to shoe. Many customers keep one pair and swap it into whatever they’re wearing that day.
Protalus landing gear guides your foot onto the correct biomechanical axis. Customers report reduced foot, knee, and lower-back discomfort, improved balance, and less fatigue during long days on their feet.
