The Brooks Glycerin Flex (2026) is a newly designed lightweight daily trainer that blends the plush DNA LOFT v3 cushioning of the Glycerin family with a more flexible, natural ride. Featuring an ultra-soft DNA LOFT v3 midsole with a 36mm heel / 28mm forefoot stack and 8mm drop, the Glycerin Flex delivers a smooth, forgiving feel suitable for easy runs, recovery days, and short-distance training. Weighing approximately 280g (US9), this shoe is designed without a carbon plate, allowing the foot to move naturally while still benefiting from Brooks' premium cushioning technology. The engineered mesh upper offers excellent breathability and a comfortable wrap, while the Green Rubber outsole provides reliable traction and environmentally conscious durability. The Glycerin Flex fills the gap between the plush Glycerin series and more responsive training shoes, making it ideal for runners who want daily comfort with a touch of flexibility. Priced at NT$5,480, it is an excellent choice for runners of all levels seeking a soft, natural ride.
