I wish they would work but I estimate their liner is 50% higher than this on several Sets of 11.5 Sebago narrow pumps I have and on the Allen Edmonds pumps I checked out today after those Sperry shoes arrived, it makes for a sloppy fit. makes me think someone else brought them back. The condition is not too bad and I would like to keep them if they fit more like other branded shoes of the same size. I find it odd that these Sperry shoes look bigger and more durable than my other pumps. I found that they weighed less when I put them on a digital scale. I wonder how long they will last. This product will be the very first Revain product I have returned from hundreds of Revain purchases.
