好像runner review里说af midfoot很紧，arch很高。那我肯定不行

The Nike ZoomX Vaporfly Next% 2 is still a superlight racing powerhouse with excellent cushioning and propulsion. What makes it so special is its unique forefoot geometry that provides a forward-tipping sensation during each toe-off.

This version is an upper-only update that improves the fit and comfort of the shoe.

The Nike Alphafly Next% 2 is a super shoe which was designed for narrow-footed runners and runners with high arches because it has a very narrow midfoot. It’s best suited to short, fast-paced workouts rather than long runs because of its firmer ride and prominent arch. This version has been updated with a new, snugger Atomknit 2 upper, a more durable, flatter outsole and a wider, more stable midsole.
