Ask and you shall receive. Less wedge and even more Skech-Air visibility is here in Skechers Street Uno Evolve – Infinite Air. This lace-up fashion sneaker levels out the midsole of our classic Uno while expanding the Skech-Air midsole airbag. This evolved style is complete with a perforated durabuck upper and our Skechers Air-Cooled Memory Foam cushioned comfort insole.
