Our Verdict
Li-Ning Chaoying Pro
Saucony Procyon Max
The Li-Ning Chaoying Pro and Saucony Procyon Max sit in a similar price range, but the Li-Ning is actually a max-cushioned trainer, while the Procyon Max is a more basic, value-oriented trainer. In terms of performance, the Li-Ning is the better shoe across the board, but it has a very narrow arch, which could make it impractical for runners with wider arches. It's also not available in stores in most Western countries, so you wouldn't be able to try it on in stores to see if the fit works for you before buying.
