The Full Story
LoveBar's deep-dive, written for humans 💕
Asics Gel-Kayano 31 and Brooks Glycerin 21 both promise premium comfort, but they get there through fundamentally different philosophies. The Kayano is a stability shoe — it guides your foot through each stride with subtle support that overpronators desperately need. Version 31 has gotten so smooth that it barely feels like a stability shoe anymore, which is the highest compliment you can pay the category. The Glycerin 21 is a pure neutral trainer that throws all its budget into cushion. That DNA LOFT foam is like running on a mattress, and Brooks has dialed in the softness to a level that makes easy runs feel like floating. The Kayano is for runners who need their shoe to do more than just cushion — they need it to correct and protect. The Glycerin is for runners whose feet need no correction, just pure comfort. Know your gait, pick your shoe, and enjoy every mile.
