With even more nitro-infused foam than before, the Brooks Glycerin 21 returns as the most cushioned running shoe in its lineup. Designed to deliver the an ultra-comfortable and smooth ride for any distance, the Glycerin 21 has never been better. As mentioned, the Glycerin 21 adds 2mm more plush and responsive DNA Loft v3 cushioning in the midsole that offers a little extra softness to a shoe that's already plenty soft. As a cherry on top, the additional cushioning does not come at the expense of extra weight. On the contrary, the Glycerin 21 weighs almost an ounce less than the previous model!
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. Rounding out this shoe is the new engineered warp knit upper that checks the boxes of being accommodating, secure, and breathable, which only adds to the supreme comfort the Glycerin brings to the table. Running farther has been made easier than ever thanks to the Brooks Glycerin 21––all you have to do is enjoy the ride.
