A lightweight. Serves its purpose in the water. Definitely increase size. I wear size 8.5 and ordered my size. I have crooked toes. The insoles fell out when I took them off after the first time.
Pros
The grandkids had a great time with them in the sea and when we go to water parks it saves their legs from getting burned on concrete.
Cons
May not provide adequate protection from the sun's harmful UV rays.
