I purchased this boot here because after wearing the one my doctor gave me for a bit, it became clear that it was much too large--my toes didn't reach the edge of the foot pad,a couldn't tighten the straps enough to be stable, etc. . I looked on the manufacturer's website and realized that the conversion from men's to women's sizes had been done wrong (it only adds 0.5 sizes instead of 1.5-2). So I bought the next size down and it's obviously correct now.
I had this boot as the last step in recovering from a catastrophic ankle injury (displaced trimalleolar fracture with ruptured syndesmosis, bonus points for getting the surgeon to use the word "pulverized"). So I didn't use the wedges but I love how light it is compared to most cam boots. Also the company was fantastic to work with, fast shipping and it got here right when promised.
