I ordered the Laplands for me and New Yorkers for my son (who can only use one hand/arm, so these are great for him). I am a size 8 W and he is a size 10.5-11 M. I ordered 43 (9-10)L and 44(10.5-11.5)XL for him and a S (7-8) and M (8.5-9.5) for myself to be sure we'd get a good fit. Short story: none of them fit. The smaller size is too small and the larger size is too large. There is no actual size 8W or 10.5 M. The result: it cost $30 in shipping charges to send 4 pairs of boots back to Massachusetts. I loved the boots; it's a horrible shame and kinda dumb, Vibram, to have chosen to clump 2 or more sizes together. I feel duped. Maybe it would help if they would tell us what size these boots actually are? If they did that, I would recommend these, they seem like great boots.
