Flip flops that fit the curve of your foot. When I bought my first pair years ago from the local surf shop, I was told OluKai warranty was for life and if they ever broke, they would be replaced free. Too good to be true and it was. When you look at the big brand flip flops, they are all close in price. I live in south Florida and flip flops are Daily wear about 350 days of the year and I wear them probably all year. Getting daily use sort of justifies the price and these compared to the other brands just contour to your feet the best. I ordered a 11 when I normally wear 11.5 and they fit great.
