After 6 months these flip flops are problem free and durable.  I like how they form to your feet after time... I walked through mud and although the flip flop stuck and my foot came out, the Reefs did not come apart... Reefs are well made.  On the negative side they are very slippery (inside, not the sole) when they are wet, which makes walking up a hill a challenge. 4.5 stars... Value purchase... highly recommended.
