I'm trying to find a pair of comfy flip flops and can't decide between reef and havaianas. I always buy flip flops and they're pretty comfy in the beginning but then when i walk more than a few hours in them they start hurting my feet. Sometimes it hurts the bottom of my feet. I had a pair of flip flops that was super soft but i could feel the strap part that connects to the bottom of the shoe under my feet and it starts getting uncomfortable after a while. Which brand do you guys prefer and why?
