Toss in the wash with cold water. Air dry. Boom.
Breaking in, but narrow
"First day of wearing was tight making it uncomfortable through the day. Not the pillow/weightless feel that I expected. The shoe starts tight and is somewhat narrow. After about 5 wears the shoe is getting more comfortable and I love the look. I commute 4 hours per day with miles of walking. I would order a wide if it were available in this style. Despite the challenges of breaking these in I still feel that I would order these shoes again."
