I'm on my 2nd and 3rd pair of NB. Being a hospital worker and on my feet all day, they are a real comfort. I have a walking shoe #810 and they are good, but a little roomy in the heel if not laced up tight. Recently bought a Crosstrainer # 454 which are even better. Love them the best. My first pair (# unknown) were great also, but I put insoles in them and made them even more cusshy. They lasted about 3 years, but I used them for work only. If I had to buy another pair, I would ask for the crosstrainers and try them against a walker. Add insoles if needed. They are expensive, I bought my pair at a discount place (Famous Footwear) for 59.00 which was a bargan. I'm cheep with a lot of other things, but when it comes to my feet, good shoes are a great investment. If your feet hurt, the rest of you is uncomfortable. Also bought Teva's for the May trip. The best kind of flip flop is made by Espirit --very cushiony as well. Good Luck!
