Glycerin 21 Running Shoe – Men's

Built for high-mileage training days and long runs, the Glycerin 21 is our top pick for runners who want plush cushioning without sacrificing responsiveness. DNA LOFT v3 foam delivers a soft, lightweight ride underfoot, while the 36mm heel stack absorbs impact mile after mile. The engineered mesh upper locks you in with a secure fit and keeps airflow moving — worth noting in Southern summers.

• DNA LOFT v3 midsole foam — soft and lightweight at 10.3 oz, with a 36mm heel / 26mm forefoot stack for serious cushioning
• 10mm heel-to-toe drop strikes a balance between cushioned comfort and natural stride mechanics
• Engineered mesh upper wraps the foot securely while letting heat and moisture escape during long efforts
• Built for daily training and long runs — handles road miles without breaking down the cushion over time
• Upper constructed with 30% recycled materials — same performance, less waste
