Where Alphafly 4 fits in your rotation
Consider it for a race-specific shortlist, then rehearse in training before committing to race day. Check comfort over your intended distance and stability at your target pace. Carbon reinforcement alone does not establish a faster shoe for you.
What the recorded measurements tell you
Source-checked record: Not published per shoe, Not published heel stack, Not published forefoot stack and 8 mm drop. Weight is a comparison input, not a speed prediction. Stack describes height, not softness; drop describes heel-to-forefoot geometry, not injury protection. One men's/unisex US 9 shoe, ounces; stack/drop in millimetres.
Construction and trade-offs to check
The record classifies the platform as neutral with soft cushioning. Carbon reinforcement is recorded; check the source for whether this is a plate or rods and how it is arranged. A performance-foam classification is recorded, but it does not quantify energy return. Confirm toe-box room, heel hold and cornering confidence yourself; these are not established by the listed geometry.
Price, availability and when to wait
Upcoming · expected 2026-10-29. The recorded price is 279.95 USD. Recorded USD price; may be colorway-specific or clearance. Not MSRP, a live quote or a stock guarantee. Do not rely on this model for an imminent race: the expected date can change, and unpublished measurements remain unknown.
Before buying or upgrading
Use the series links to check the previous Alphafly model, but only draw numerical conclusions when both entries have comparable, dated source measurements. Keep a comfortable existing shoe unless the new version addresses a specific need. For a new model, verify sizing, width options, outsole and return policy rather than inferring them from weight or price.
