The 361º Spire 4 for men is technically a high-cushion, neutral shoe, but the QU!K Spine carbon fiber shank under the midfoot gives it the stiffness and resilience found in some shoes classified as supportive. This won't bother the neutral runner; it just makes the Spire 4 a great choice for long, long miles or a solid base for orthotic footbeds.
The Spire has a great initial feel that endures thanks to a MORPHIT internal bootie construction and pressure-free tongue. The fit is secure but flexible. The midsole is a combination of 361's proprietary QU!KFOAM, a durable PU coated EVA/rubber blend, and QU!K Spring+, a lighter EVA foam that promises more bounce to the ounce.
The upper of the Spire 4 is a breathable knit mesh. The outsole is designed for enhanced ground contact and a balanced toe-off. All-in-all, this shoe reflects attention to detail that should make it a fast favorite of yours.
