The 361 Degrees Spire 3 maintains its position in the 361 line up as their most premium neutral on a regular basis road running shoe but receives a revamped upper and an up to date midsole design. What’s New The midsole was once relatively redesigned to give a boost to cushioning upon heel have an effect on even as increasing responsiveness in the forefoot. The heel-to-toe drop lowered from 12mm to 9mm. The new engineered mesh upper will increase comfort even as remaining lightweight and breathable. Featuring 361’s painted QU!KFOAM midsole material in an instant under the heel gives the Spire 3 a softer landing with better have an effect on absorption. As you move to the forefoot, the responsive QU!KFOAM material slopes down and sits underneath a firmer material which gives the shoe a springier toe-off. To increase efficiency and give a contribution to the springy toe-off, designers included a carbon fiber plate in the midfoot of the midsole. Moving on up, the Spire 3s internal midfoot webbing and lightweight mesh upper work together to comfortably hold your foot in place all through your stride.
