Bought to replace an old pair of Sperry pumps. they look good, they are comfortable and the sole has a nice grip. My problem is they make my feet sweat like crazy! I can sit on my couch and wear them for 10 minutes and my feet get sweaty. The insole is foam rubber and the lining is something synthetic. they just don't breathe at all, and while they appear light, they get hot very quickly. I'm afraid to wear them without socks because they smell and the reason I buy pumps is because I want to wear them without socks. I had my last pair of Sperrys for a few years and never wore socks with them. My feet didn't sweat at all. They look great but I would advise anyone not wanting to buy unless they change the interior materials.
