The tread in the picture is fabric like felt or cotton. Haven?t heard anything since and still haven?t received a replacement weeks later. I admit that these flip flops are comfortable and my feet dont hurt while wearing them, but the quality is sub par. I don?t know where all these positive reviews are coming from. I made the leap for the savings and Im happy with my purchase. This stuff is absolute garbage I have tried to repair it with duct tape but it?s clear that?s not going to last. Returning both. Try some . I had ordered a half size down and these are still large on my feet. RAZER KRAKEN 7.
