Menuda sorpresa! 5 all day long, but I got an 8 in these. They are easily the longest lasting and most comfortable sandal I have ever worn. ***UPDATE [Cleaning]: it is currently 19 February and Ive only had to clean the trackball twice. I figured it was due to defective velcro. I am normally a size 7 so I got a size 7 and they are way too small. I have plantar fasciitis and Crocs were one of the few shoes I could comfortably wear. Got these to hang windchimes and birdhouses on my patio. Mit Hülle ist der Controller rutschiger als vorher. I wanted to wear them every single day.
