I tried on several sketchers shoes with memory foam hoping to find one that I could walk in for a few miles. None of them fit that bill, but I decided to keep this one anyway because it was a good balance of casual, comfortable but not sneakers for a decent price ($31 black mesh size 6.5). I normally wear a size 7-7.5 and have a narrow heel with slightly wide feet. I needed a 6.5 in this. The length is a touch short but the 7 was too wide, long and my heel just didn't stay put. It does rub my heel a bit when I walk and will probably blister if I walk long enough, but I plan to only use it for casual short outings. I do like the black mesh upper, it goes well with all sorts of outfits. Plus the memory foam footbed is super nice.
