Hello, not easy to find. My husband also wears a size 15, peloton only goes to size 13, as we were told. After searching eBay, Amazon, etc., I purchased the cages to go with the bike. Good luck on your search, I hope that you find them....😊Hello! Please help! I can not find size men’s 15 shoes! I ordered the bike and peloton assured me how easy it would be to find shoes for my husband and I still can’t! Please help!
