REEFDreams Women's Flip Flop, Memory Foam Cushion Footbed, Faux Leather Satin Lined Strap

What is the weight of the size 8?

I am looking for a pair of flips to wear around the pool. Do these get slippery when the inside and sole get wet? I will be walking on concrete.

could these be made for men?

Are these vegan?
