There are, however, certain shoes on the market with effective rocker soles. PW Minor manufactures a variety of rocker-soled shoes. Hoka manufactures several decent rocker-technology running shoes, and Dansko makes some very good rockers for folks with ball-of-foot discomfort and big toe joint pain. The advantage of rocker shoes is that they make the foot more adaptable to different types of terrain. This is particularly important if you plan to run long distances in hilly areas or if you want to reduce the risk of developing chronic foot problems later in life. However, not all runners benefit from using rocker shoes. If you're one of those people who likes to run in true-to-size shoes that fit perfectly right out of the box, then rocker soles aren't for you. You should also avoid rocker shoes if you have sensitive feet or plantar fasciitis because they won't be able to provide proper cushioning. In conclusion, there are rocker shoes on the market today that can help prevent many common running injuries if used properly. However, not everyone will benefit from using these shoes so it's best to try them on a shoe tree first and see how your feet feel after walking around in them for a while. If you don't like them, no problem - you didn't pay for them!
