Under Armour Spine RPM, $100
9.7 oz.; 7.4 oz.
Fit: This shoe has a comfortable and close fit, with adequate space in the toebox but little excess room. Our testers surmised it might be best suited to an average or narrow foot.
Feel: Although very light relative to their size, this shoe exudes a firm feel that borders on stiff. The firm spine design feature running from heel to toe in the outsole and midsole keeps the foot locked in place, but testers also felt it limited the shoe’s flexibility and agility.
Ride: The ride is well-cushioned but decidedly firm. The chassis offers a significant amount of structure and support, making it most appropriate for a runner who typically runs in a stability shoe or for larger runners who appreciate a more significant platform.
