I wish they would work but I estimate their liner is 50% taller than several sets. From the 11.5 Sebago skinny pumps I have and the Allen Edmonds pumps I checked out today after these Sperry shoes arrived, this makes for a casual fit. I don't mind that the shoes arrived worn so I suspect someone else returned them. The condition is not too bad and I would like to keep them if they fit more than other brands in the same size. I find it odd that these Sperry shoes look bigger and sturdier than my other pumps. I found that they weighed less when I put them on a digital scale. I wonder how durable they will be. This product will be the very first Revain product I have returned from hundreds of Revain purchases.
