For shoes that are quick to put on and easy to wear, take a look at Overstock.com's collection of slip-ons. These comfortable shoes are an excellent choice when you need to slip into footwear to run a quick errand. The easy-fit backless designs are great if you have your hands full or have difficulty bending down to tie laces. Keep a pair of slip-ons by the front door for when you need to take out the trash or walk the dog. Clarks' ballet flats and Mary Janes combine daylong comfort with attractive appeal, while Skechers' walking shoes provide support during town or country strolls. Perfect for vacations, Ugg's espadrilles protect your feet from hot sand on the beach. Pop a pair of rollable shoes in your handbag for emergencies, such as broken heels or straps, or to slip into if new shoes start to pinch.
