Did not provide arch support, as claimed. Size was too big even though this was size 10 and I normally wear size 10. Seller says refund can be made only if item is defective.
I had ordered another pair of flip flops from the same seller. But, mysteriously disappeared AFTER shipment. When I went to order a similar pair, the price was higher. Anyway, I ordered it. But guess what, that also dudapoeares AFTER shipment. 
The only pair that arrived was an ill fitting, poor quality one
