This brand new running shoe is a direct update of the former prodigy running shoe.
A running shoe is very different from a general athletic shoe in that it is constructed uniquely for running.
In general, a running shoe is designed for forward motion as opposed to a general athletic shoe which is designed for lateral (side to side) motion.
On the other hand shoes that retail for under $50 can be suspect and while they may look like a running shoe generally have excessive weight or are of poor quality.
Talk to the salesperson at this point about any good running shoe sales that are currently happening, or coming up in the near future.
