Toss in the wash with cold water. Air dry. Boom.
Need more toe room and cushion
"I bought these for a convention event after hearing the cost was worth the investment due to their reputation. Standing for 8+ hours these flats came up short, up front I need mode toe room so my toes weren’t scrunched together and instead could spread out comfortably and the cushion wasn’t sufficient for long day wear as the day progressed it felt as though I was barefoot."
