I bought a pair of the professional clogs about a month ago. Size 38 (I'm a size 8 in american sizes). I liked them at first and it helped with my plantar fasciitis, but it has been about a month and I STILL feel like they're not broken in. My toes and the top of my feet hurt after my shift. The tips of my toes are black from rubbing against the front of the clog during the day, but I thought I had adequate room since I am able to fit a finger in the back of the clog . Has anyone else had this problem?
