Toss in the wash with cold water. Air dry. Boom.
Works well on narrow feet
"I'm wider in the toes and narrow through the rest of my foot making standard sizes difficult. This style ties up far enough that I can adjust the ties firmly mid foot while having wiggle room for toes. I wear them with a Dr Scholl's orthotic for optimal arch support and ball of foot cushioning. This is a great color to wear with jeans."
