Kōko'o Waterproof Flip Flop

Sorry to leave this feedback as I already own 2 pairs of olukai shoes and love them. I bought these flip flops and packed them in my bag, headed to Cancun for a week vacation. After the first day, my feet were blistered to the point of not being able to wear them the rest of the vacation. I walked bare foot almost exclusively, when allowed, thereafter. The blistering was odd. It occurred on the top of my feet, behind my big toe. It was due to the “connector” for lack of a better term, between the sole and top of the flip flop. Sad to say, I’d have been better off, packing a pair of $5 dollar old navy flip flops, but i did not discover this until it was too late, and I was out of the country. Disappointed.
