I just used alcohol wipes. My daughter loved them but unfortunately 11/12 turned out to be the biggest size available and four my 4 year old was a tad to small. I don?t think anyone would be disappointed in this shoe. The problem is the hooks bent within 30 minutes of filling the bags and it dropped. It was bought for my nephew, however I have not heard a complaint. I continue to try and plug it into the Bluetooth (struggled due to New port so stuff fit) and I get burned from the usb. This design might suit those who want a classic-looking semi-dress shoe. These shoes however are so comfy, that I can wear them and stand in them for several hours without having knee pain 24 hours afterwards. The back of of the boots are reinforced with a sewn in layer of wool. I can slip them on and off easily thanks to the open back.
