My brother had a pair of these Skechers on a recent visit and couldn't stop commenting on how comfortable they are. Spring. I had to find out for myself so I bought this pair with memory foam inserts. Respond when they feel comfortable? Surprisingly comfortable and lightweight, it feels like walking on clouds. You can wear them all day straight out of the box. They are soft, with good support and close to the heel. I considered going down a size in half as they are a slip on style, but went with the recommended size which I usually wear and 10.5 was perfect. Definitely look at another color now to buy the next one.
