What kind do you guys wear? I have a pair of Chaco Flip EcoTread and also a pair of Etesia EcoTread and both give me blisters under my big toe and on the ball of the foot.
OluKai Ohana and Cobian braided leather Bounce seem to work best for me for some reason. Nothing else even comes close, although I do like the Sketcher Toneups, Orthoheel Tides and Waves, Fit Flops, and Montrail Molokini. If I can find them I also like the Volatile Keralee (but don't care for any of the other Volatile flip flops, even though some look alot like the sole on the Keralee---they just fit tighter in the straps and the soles are not as comfortable for some reason). Volatile Keralees I can wear all day long though. I also recently bought some Flojo Exena's that I'm loving right now. They have a thick, soft, bumpy sole on them, that just cushion your feet.
