Which one of these stability trainers is better for you?
Similarity and differences: Gel Kayano 30 vs Gel Kayano Lite 3
Sole unit: Gel Kayano 30 vs Gel Kayano Lite 3
The Kayano 30 has one type of foam in its midsole: FF Blast+.
The Kayano Lite 3 has a single-density Flytefoam midsole. It has smoother ride transitions than the Kayano 30 but it has a stiffer forefoot due to the absence of FF Blast+.
The ride of the Kayano 30 is softer than the ride of the Kayano Lite 3 due to the FF Blast+ in the midsole so it’s better for longer runs at slower paces.
The firmer, lighter Kayano Lite 3 is better for shorter, faster runs. It’s more nimble than the Kayano 30 and it feels more snappy.
Both trainers have gel in their midsoles. The Kayano Lite 3 only has a small amount in its forefoot but the Kayano 30 has silicone gel in its heel.
Stability is better in the Kayano 30 than in the Kayano Lite 3 due to the extra stability elements. It has a Dynamic Duomax medial post which the Kayano Lite 3 doesn’t have.
On the outsoles, both trainers have firmer, more durable AHAR + on the heel, with softer AHAR rubber on the forefoot. The biggest difference is that the Kayano Lite 3 has a filled up midfoot medial side whereas the Kayano 30 has no rubber on its midfoot so the Kayano Lite 3 has the more durable outsole.
Upper unit: Gel Kayano 30 vs Gel Kayano Lite 3
