I wear an 8 1/2 shoe, and first ordered on product recommendation to go up a size, to women's 9. Wrong way, folks. So after returning and getting an women's 8/men's 6 I still am sliding around in this pair. They're still way too wide at the heel end, and about a half-inch too long. I do think a women's 7 would be too small and am tired of returning. So I'll keep them and just be very careful going up hills and stairs. Wish they still made crocs in Canada!
