Nike Streakfly 2

A track-spike-inspired racer built for mile-to-5K distances and forefoot strikers, delivering exceptional pop and turnover on road courses. Narrow throughout with a racing fit that demands true sizing or a half-size down; traction falters on wet surfaces.

Believe in the Run Youtube

The best dedicated 5K/mile racing shoe Believe in the Run has reviewed in nearly a decade — exceptional pop and turnover for short-distance racing, but punishingly specific in fit and use case.

Best for: 5K and mile racers who land on their forefoot and want the lightest, fastest ride possible.

Massively improved over v1 as a race shoe — completely reinvented as a road track-spike for short-distance racing. In the right hands at mile-to-5K distances, it could do amazing things.

Best for: Mile, 3K, 5K road races and short speed sessions for forefoot strikers with strong calves.

Andrea's hands-down favorite shoe ever for the road mile distance — used it for two PR mile races (4:59 and 5:20) on consecutive days. Versatile from mile up to 5K for non-spike racers, but watch for traction issues on wet surfaces.

Best for: Mile to 5K road races for forefoot/midfoot strikers who don't want to race in spikes.

It's a buy — first 10K in four years, raced wet Boulder Boulder, no complaints on traction or fit. Loved it enough that he's now thinking about a 5K race specifically to use it again.

Best for: 5K racing primarily; capable up to 10K but at the edge of its range.
