I ALWAYS wear a women's size 11 in every other brand, but the Gdefy shoes came and are so small that I can't even get my custom orthotics inserted into them (clearly their sizing is wrong). They claim to have a 60-day no pain returns and exchange policy, yet refused to exchange for the correct size (they only make women's sizes up to 11 so I would have to go to a men's 10 for the equivalent of a women's 11 1/2) and for some absurd reason they will not exchange women's shoes for men's sizes even though I wanted the same exact shoe just half a size up! The extremely curt representative said I would have to refund (and it would take 30 days to go back on my credit, plus I would have to buy a new pair, but I bought the original unworn pair with holiday promotions they then refused to apply to the new pair. When I asked to speak with a supervisor I was told it would be 3-7 days until I would receive a callback. Only then did I search reviews on the company to learn the owner of the company is being sued for false claims about their shoes and tons of negative reviews about their customer service. BUYER BEWARE!
