The Nike Free 5.0+ is a hugely popular shoe mainly for casual wear, but it doesn’t often get the credit it deserves as a running shoe. A lot of Nike shoes don’t work for me because they tend to fit narrow, but the Free 5.0 fits comfortably and I enjoy running in them.
If you like a flexible shoe that runs super quiet and feels like a slipper then these are definitely worth a look. And if they don’t work out as a running shoe for you, you have a comfortable shoe that will serve very well for walking around town. And if you don’t want them for casual wear, they retain value as well as any shoe out there and can be sold on Ebay for close to purchase price even with a few runs on them (did this a few years ago with the Free 3.0 v4).
