I buy these after realize my worn out Merrel sandal be no longer build ... I be not keen fan , and I still think they look a little funny . but , they fit well , seem well make , and they feel great . I have wear they to work for a week , and walk 5 mile around NYC and I be still happy . I think my proper size be a 9.5 , and I hear these run big , so I order a 10 , and that seem right . I kind of have to work to get they on , and I do not slide around in they . the elastic lace seem to do little . I imagine they will stretch out a little -lrb- not too much I hope -rrb- and the lace will be useful .
