ASICS Hyper Speed 4

Budget lightweight speed trainer/racer (215 g) with simple FlyteFoam and a traditional low-stack feel. Great value for intervals, tempo days, and racers who don't want to spend supershoe money. Skip it if you want plate propulsion or modern max-stack cushioning; this is an old-school flat. Note: low-profile release with minimal US media coverage; US pricing estimated from line pricing ($90-110) and stack height is disputed across retailers (29.5-32 mm).
