REEFFanning Men's Bottle Opener Flip Flop, Arch Support, Durable Outsole, Water Friendly

Hi. Can these be worn walking around paved streets, shopping, etc.? Thanks

Will 9d(m) us fit a 8 and half?

Will it be ok for tropical rainy season? Does it take long to get it dry again? Any persistant smell?

How much do they weigh?
