My 2nd pair. Love haviannas.
I wear 11.5 A, 41-42 slim, fits perfectly. I like the fact you can select different colors in a size that fits well.
I live on a tropical island so flip flops are the standard footwear. Nothing beats Havaianas for suppleness, durability, style and comfort.
Perfect flops. Worth the extra cost, the quality is very good for a flip flop and they don't slip or chaff.
