Whats the difference between High performance shoes and Cross-trainers?

• I'm looking for a type of workout shoe, one that can do step aerobics, tae bo and aerobics. I'm getting confused with all the different types of shoes listed. I see 'High Performance' and then I see the tried and true 'Cross-Trainer" types listed. Such as listed at Kohl's the Athletic shoe options are Running, Trail, Cross-Training, High-Performance, Hiking & Walking and Sandals. What workout exactly are High Performance shoes for?

• Answer:

  DP About fifty buck$,,,,, Bada Bing! :-) A High performance shoe is a high performance running shoe. Usually designed for distance running. The Cross-Trainer id a shoe designed for multiple activities, Gym, run, lifting, an all around sports shoe. Do not put much faith in the names my friend. It is marketing to the max. Instead rely on the fit and comfort test. Especially in the firmness, and padding, of the arch area and the forefoot. In the routines you mention those will be the points of most contact, Soccerref
