If you want comfortable public service shoes, get the Rocky Alpha Force work shoe. It's made with the extremely comfortable Air-Port footbed that provides cushioning and support. The polyurethane material used in its insole is known for its cushioning while not bottoming-out features. Some open-celled foams feel very comfortable to the initial touch, but tend to break down faster than a product made with polyurethane. Plus, it is extra thick in the heel contact area. This provides additional underfoot comfort to the wearer.
