There are a slew of deals on sneakers that make for great walking shoes, like the customer-favorite Skechers Newberry Slip-On Sneakers. The lightweight shoes feature a cushioned insole for support. Plus, they have a slip-on design and elastic lace closures, meaning they don't have shoelaces that require you to hunch over and tie. 

If you're looking for slip-on shoes without any sort of laces, opt for the Dr. Scholl's Slip-On Sneakers, which have a removable cushioned footbed. They come in three colors, including dreamy blue and sage pastels.

Just in time for the warm weather, there are plenty of sandals on sale. To hop on the platform shoe trend, check out the Eileen Fisher Touch Platform Sandals while they're up to 48 percent off. They have textured soles, which helps with stability. And their platform design leaves plenty of room for a foam-cushioned footbed, meaning you'll get some height without the pain of heels.
