You can climb the stairs fine. It's the way back down. You stop at the top now — one hand on the rail, one step at a time, both feet meeting on every stair. You plan which arm carries the laundry so the other one is free. You let people pass you on the steps at church. You've tried the sleeves and the straps; there's a drawer full of them. None of them are with you on the way down.
Going down, the muscle above your knee is the brake — catching your whole weight, one leg at a time, on every step.
The AirPad puts a pocket of air right under the kneecap, between the step and the joint. Press air slowly and it gives. Hit it hard and it pushes back harder. So it stays soft on an easy step and firms up on the one that would have caught you. It doesn't squeeze your leg and it doesn't stiffen your step. The rail can stay where it is. This stays on your knee.
Every step down, that force has to go somewhere. The AirPad PRO gives it somewhere else to go.

The adjustable strap fits patella circumferences from 11 to 18 inches. The dual-knot adjustment system allows you to customize the fit for your specific needs.
Most people use both, and we'd never tell you to leave your poles at the trailhead. Poles give you two more brakes — but they're in your hands. They're not there on a scramble, or when they're strapped to the pack because the terrain got technical. The AirPad works at the knee, and it's there for every step down whether your hands are free or not.
No. The interior is ribbed non-slip silicone that anchors against your skin instead of gripping by squeeze, so it stays where you set it through a full descent. No stopping every mile to pull it back up. If it does move on you, that's almost always a fit issue — email us and we'll walk you through the adjustment.
Yes. It's open at the back of the knee rather than a full sleeve, so there's no wrapped-leg heat and nothing soaked through on the climb. Skin-safe silicone, no rubbing under a liner. Most people forget it's on.
No. It sits under the kneecap rather than wrapping the joint, so you keep your full range of motion and you still feel the ground under your foot. It's built to move with you on uneven terrain, not to hold your leg still.
Day hikes, multi-day backpacking, alpine descents, rim-to-rim, thru-hike sections — anywhere you're going down for hours with weight on your back. It also works fine for trail running, stairs and everyday walking.
Most people feel it on the first descent, once they've got the fit dialed in. Put it on at the trailhead or at the summit before you turn around — plenty of people only wear it on the way down.
