Fit: The fit is tru to size, I normally where a 10.5 shoe or a 10 depending on the brand and these in a 10 fit my feet perfect so I would recommend getting the size sandal you normally would wear.
Material: The top material that your foot steps on is very comfy. It has a really dense quality foam material, not like a cheaper material like the $1 sandals at old navy (nothing bad about those) but this material feels alot better on the foot and more "luxuirous". The mid materail, the white, is a harder foam, probably for support. The bottom is made out of what feels like the same material/rubber they use in the bottoms of their shoes whis is nice due to its durability and you won't be sliding everywhere like cheap sandal that use the same foam material all the way throughout the sandal. The thong or strap part feels very durable, its not super cushiony but they are pretty comfortable.
Design: Exactly what the picture shows. Im sure the white "DC" logo on the top will turn brown or black from stepping on them after a while.
Overall: great quality sandal for the price. I usually get the cheap $1 sandals from elsewhere but I've like DC for comfortable durable shoes and these are just it.
