Product Details:

With even more nitro-infused foam than before, the Brooks Glycerin GTS 21 returns to deliver an ultra-comfortable, smooth, and stable ride for any distance.

Updated with 2mm more DNA Loft v3 cushioning in the midsole, the Glycerin GTS 21 offers a softer and bouncier underfoot experience than ever before, and the cherry on top? It does so without adding weight. For runners in need of additional support, Brooks' trusted GuideRails support system rounds out the midsole to help guide the foot straight and keep your transitions smooth and balanced. 

Bringing long-lasting traction to the party is the new RoadTack rubber that is strategically placed in the outsole to deliver the grip needed to rack up the miles. Meanwhile, the shoe is rounded out with a new engineered warp knit upper that checks the boxes of being accommodating, secure, and breathable, which only amplifies the supreme comfort that the Glycerin brings to the table.

Running farther is now easier thanks to the Brooks Glycerin GTS 21––all you have to do is enjoy the ride.
