Full Review
The Nike Alphafly 3 arrives as a proven performer in the racing category. The midsole delivers a plush, well-cushioned feel that absorbs impact beautifully. At 8mm of drop, the transition from heel to toe feels moderate and versatile, accommodating most stride types.
Fit-wise, the Alphafly 3 runs slightly narrow in the midfoot with a snug, race-tuned feel. At $285, it is a premium investment best saved for race day.
The carbon fiber plate adds propulsive snap to each stride, particularly at faster paces. This is a shoe that rewards runners who push the pace. Overall, the Nike Alphafly 3 is a race-day weapon that earns its spot in any race kit.
