Size ordered was a 12 - felt short but kept it because I liked the shoe and thought if my foot didn't slide into end of the toe area I would be OK. Also I hate to return things. Big mistake, feet do slip and my left big toe is affected - should have returned the pair right away.  Size is not true.  Ordered two other models of Women's New Balance size 12 and they are fine.  This shoe appears to run 1 size smaller than it really is.
