I ordered 2 pairs of shoes with a memory foam pad inside and 4 prs without memory foam.  My husband tried on a pair of the shoes without memory foam and said they would be fine, assuming all 6 pairs would fit the same  Upon starting to wear the pair with memory foam he said it felt like his toes were dropping off a cliff and felt a little snugger than other pairs of the same shoe.  Unfortunately it is too late to return so we are out of luck on getting a refund.
