Unfortunately the sewn in neoprene sleeve is so cheap & thin that;it does not protect you from the hard and lumpy exterior parts and edges.And it buckles and scrunches up under the tension of the elastic straps attached to it- which renders that support feature uselessWhen I tried walking in this brace, I had to remove it in less than an hour.Even with thick socks it caused a kind of friction / pressure burn from the edge of the hard shell.Didnt do much walking the 2nd time I tried it… mostly standing on a step stool, and after 1-2 hours still had swollen red welts from the hard plastic edges of the outer shell digging in to my lower calf -No matter how I loosen or tighten it there’s a different set of welts due to skimping out on the neoprene sleeve, which is paper thin.I have multiple other braces and getting welts and pressure sores is not something I’ve experienced before.Super disappointing given what it promised.
