Their sizing is strange. They have one size called 6 to 6 1/2 and the next size is 7 to 7 1/2.  Had to purchased two pair since I wear 6 1/2 to 7.  One was too small and one too big.  Returned one pair and sold the other pair since I had worn them once (taking a $50 loss).  Not recommended unless you want to use an insert.
