Good sneakers for the money. Don't place too much hope on carbon; it will only add a little speed, especially if you're running at 4.30 or faster. In general, Li-ning is top and worth the money; this is already my second pair of sneakers from this brand, and the third one is on its way. After them, I don't even look at well-known brands anymore; I think they are overpriced. First I took the Superlight model, now these are on the way: Red Hair 8 Pro.
