Since I got them, the right shoe makes a clack clack sound with every step when I lift my foot off the ground, as if I've stepped on gum or something else sticky. It sounds so loud that I feel embarrassed when walking in a closed space because people turn to see where the sound is coming from. I washed them, I washed them again, no change until I threw them away. Also, while I wear size 39-40, these in size 40 came out very tight, and initially, I exchanged them for size 41 which I never wear, so they have a narrow fit.
