I have high arches, medium to wide feet and my left foot is almost a full size smaller than my right, haven't found a shoe manufacturer that accommadotes that yet. For me, disregarding my size issue, Sportiva's are hit and miss on fit, have a pair of trail runners that fit well but haven't had much luck with their boots mainly because of width and the high arch. Same with Scarpa, just don't seem to fit me well which is a shame because Scarpa and LS make really nice products. Lowa, Kayland, and Garmont have worked well for me, particularly Kaylands. Three different models of Kaylands have fit me well, from light hikers to a heavy hiker that I use for 3 season mountaineering. The down side is that Kayland no longer distributes in the U.S. so it's either finding boots that are still hanging around or ordering from a retailer in Europe.
