I've worn crocks  (mules) all my life and consider them the best priced, best quality mule on the market. They are true to size and though half sizes are not available, the way they "adhere and stretch" around your foot as you wear them is "why I would say" is the reason they tell you to get the smaller size if you wear a half  shoe size vs. the bigger one. Very comfortable shoe and the suede colors are great with jeans, dress pants, shorts pajamas, etc. I dress them up and I dress them down. They look classy and give you height with the two inch heel but feel like you're in flats. I ordered, they shipped and I received them perfectly packaged promptly in 48 hours! Kudos!
