so i just got these and have been wearing them around the house so far. first impression is that they are light and stiff. i am a size 9 in shoes and a 9 1/2 in every boot. went with the 9 /12 in these and they fit really well. the heel is not as tight or secure as the nepal evo(same size) but the footbox feels just slightly more roomy. the gator zip extends all the way to the toe box area, and secures fairly well around the ankle. have tried them stock, and with green superfeet, with a combination of socks and liners, tried smartwool mountaineering socks with liner and they have a really nice fit, same with a liner and mid wieght socks. i do feel that since the lighter construction that the nepal evos will be sturdier but the kaylands have a much shorter break in time. all in all really impressed but for my foot shape of slightly narrow with a narrow heel mi will be going with the nepal evos. the "walkability" of these on flat ground is almost as good as the evos, so long approaches on trail will be of little discomfort and technical ability with these being so stiff will be great.
