Toss in the wash with cold water. Air dry. Boom.
Great vacation shoes
"Walked in these all through northwestern France and Paris, they were brand new. No blisters, feet were comfortable other than being tired at the end of long days. Just wish I had ordered a smaller size, wasn’t sure what to order as I wear larger running shoes than everyday shoes. Ended up just sewing the strap a little to make the fit better. They seem very durable so far!"
