Altra

3-Sum Running Shoe - Women's

Details

• PRS2-W last offers a narrower heel, longer arch, narrower midfoot, and a higher instep than the men's PRS2-M last
• Seamless synthetic upper feels smooth against your foot and doesn't require you to wear a sock inside
• 5mm Contour footbed provides support and minimal cushioning to keep your foot comfortable without adding unnecessary weight
• Soft, EVA midsole provides cushioning and reduces impact on your ankle and knees
• Asymmetric, quick-draw laces provide a fast and secure way to get these shoes on and off during transitions
• Midsole features an Altrabound top layer that feels springy so the midsole returns energy to help you glide through your stride
• Zero Drop Platform (0mm) features a 1:1 heel-to-forefoot height ratio, which means that your heel and forefoot sit exactly the same height from the ground
• Blown rubber outsole offers moderate flexibility to complement the natural-running style of this shoe and provides ample traction on the road
• SpeedPod lugs are mapped to support the bones of the foot for the most natural feeling throughout foot strike and toe off
• Heel and forefoot drain holes allow water to move quickly out of the shoe and away from your foot
• Together, the midsole and outsole make for a 18mm stacked height from the surface of the ground to the bottom of your foot
• Item #ATR0008
