I've worn them 4 times hoping that they would feel comfortable after each wear because I've heard that they're suppose to conform to your feet, but the shoe shape is just not for me... They're so cute would love to keep them, but make my feet/back ache so I'm letting them go! I'm normally a 7-7.5 in womens but wanted to wear these clogs with socks and sized up to a 8-8.5 (EU size 39) and they fit perfectly with socks on!
