Here’s my compilation of some of the traditional running shoes (includes trainers and racers) available today based on the shoe technical specifications provided by the footwear manufacturers where available. We are missing specs from Nike and New Balance. I’ve scoured the web for some of the numbers from other runners and web sites and they appear below (after my table) – no guarantee that they are valid.

Caveat: There is usually variations in the amount of elevation in the insole, strobel, outsole, or other parts of the shoe. But for the majority of running shoes, the differential stays the same. With some models from Saucony, Nike, and Newton, that may not be true.

Thanks to ‘G’ for pointing that out! (RSS)
