I took these flip flops on our trip to Puerto Rico. I had never worn them before. We went kayaking, hiking in the rainforest (in the rain, go figure), walking on the beach (many times), hiking on slippery rocks along the river and riding ATVs. After all that they still look brand new! They are very durable and have non-slip bottoms. They are the most comfortable flip-flops I have ever owned. No issues with them being new either, no blisters. They did not stretch out after they got wet. I just bought another pair in brown and plan to buy a pair for my teenage daughter. She will be the true test as to how durable they are
