After a recent incident where I ended up rolling my ankle into a midlevel sprain I needed a boot. My wife found this United Ortho Short Air Cam Walker Fracture Boot and - thanks to Amazon’s overnight Prime option - we bought it and had it here the next day. After almost three weeks I can say this United Ortho Short Air Cam Walker Fracture Boot has been a great asset for me, helping protect and give a place to heal my foot, while allowing me to also safely walk as soon as I was able to be up on it.The United Ortho Short Air Cam Walker Fracture Boot is mostly well designed with good materials and has stayed strong throughout. I will say, due to my injuries I have been unable to put the United Ortho Short Air Cam Walker Fracture Boot on by myself throughout. My wife has had to do it. From my standpoint, it would be a little hard at times - on and off can be a bit painful, but as we got used to it, less issues happened each time. We also learned a few “short cuts” such as having the inner boot inside the outer boot and me setting my foot into the whole unit - rather than putting it into the inner boot and setting both into the outer boot - saving me pain from the narrow opening.The pushbutton air filling mechanism is in an... okay spot. I again could not do it myself until recently, but even for my wife it meant a kind of “bending” to reach it for her. And it requires a pretty solid, hefty pumping motion in order to get the air in. You’ll work for it. But with each pump I could feel the air entering and could talk her through what and how much I needed. So from that standpoint, it worked well. And the mechanism works outstandingly well when emptying, Over the three weeks I only - somehow we still can’t figure out - accidents released the air once.The inside feels good and comfortable, but equally supportive even without the air. But that air felt so much better once in. I never felt weakness nor discomfort when wearing or walking. I never wore a sock in there, and mostly remained cool and comfortable, but maybe twice I did get a bit hot. Nothing slipping off the outer boot didn’t help. Even the inner boot was comfortable alone and while it didn’t give them the same level of support, it reminded me to watch out for my ankle and kept it from giving way - I never walked with it alone.The United Ortho Short Air Cam Walker Fracture Boot included two cushioned pads you can set inside, securing with velcro, in order to provide more cushion and aide in proper fit. We used these every time and they worked well. I do wish they’d include a second set as these two - while still being good and can be used in the future - do take a bit of a beating. It would be nice to have that second set as a back up.In the end I’m still using this United Ortho Short Air Cam Walker Fracture Boot for another few days to week, and from the first time we slipped it on, my wife and I are both happy with how well it worked. It has helped me through and I am grateful for it. Any “cons” are so weak they would not keep me from using this now again, or getting another just like it (hoping I never need to, that is).
