I purchased the gravity defeyer shoes on 10/30/21. I took them as my only pair of shoes on a cruise. The construction under the big toe broke down and I was walking on my toe which had surgery. The shoe structure disintegrated, I walked on my big toe very painfully and had to buy new shoes when we returned on 12/ 31/21. I have written 2G defy and emailed them with Proof of purchase and have at this time, 03/12/22, not heard a word from them.
