This week’s episode is all about the As—A for Amandas and A for Adidas. Our guest Amanda Wolkowitz, who hails from Chesterfield, Missouri, trades in her Brooks Ghosts for the Adidas Ultraboost 5X.

The Ultraboost 5X is the Ultraboost 5 “uncaged.” The Ultraboost traditionally has a TPU lace cage system that wraps over the midfoot for stability and fit. While some runners like their feet “caged,” others feel that the TPU adds extra weight and puts pressure on their instep. The Ultraboost 5X version removes most of the TPU over the foot, yet stays true to the Ultraboost’s other iconic features: a sock-like, tongue-less knit upper; Torsion System to promote a smooth ride; and, of course, lightweight Boost midsole foam for high rebound and durability. See what Amanda thought of the Ultraboost by watching the full episode.
