Went for knee brace. They had sizes XS, M, & L, no S. He gave me the Medium & it is too big. Guy insisted it fit, but he had to cut about 4" from the straps & "pleat" it at the thigh. The calf gaps, even though he said it should be snug so as not to fall down. It is not comfortable & slides down leg. They should have all sizes in stock instead of trying to jerry rig something that is obviously too large. I asked when he would have size small in stock & he said maybe they would order some. Maybe??? When dealing with an injury & trying to heal as quickly as possible it is ridiculous that they do not have the proper braces in stock.
