The design and engineering of adidas’ Boost material have provided a ride that has great cushioning and now with the introduction of the Boost ST, a shoe with stability to match. The upper is a stretchy, engineered mesh with different “zones.” The forefoot offers the most stretch with a band-like, bunion-friendly region over the metatarsals. The midfoot features a supportive TPU saddle that cradles the foot and anchors the lacing. The heel features the same thermoplastic heel counter and pull-on tab seen in its sibling, the Ultra Boost. The midsole is also the same: all Boost foam with its bouncy, durable cushioning. The medial side is filled in beneath the arch for extra support on landing. On the medial sidewall, a thermoplastic support links the saddle to the outersole, stabilizing the ride without affecting the cushioning. The outersole is a Continental rubber compound that stretches elastically to keep the shape of sole consistent through the gait. Its combination of a resilient ride, good stability, and accomodating fit earned the UltraBoost ST our award for Best Shoe in the Motion Stabilizing category.
