Verdict
The Under Armour Assert 10 Kids is a solid performer — a kids running scoring 81/100 in SoleHunt's data-driven evaluation, drawing on 0 consumer reviews and 0 independent expert tests. Tipping the scales at 200g, it is notably lightweight for a kids running. The 24mm heel stack — a minimal stack — delivers a medium-firm ride at 34 HC, returning 48% of impact energy and feeling cushion-focused rather than reactive underfoot. Geometrically, the Assert 10 Kids runs on a mid 8mm drop that works with most running gaits, with a 16mm forefoot stack that maintains the traditional heel-elevated geometry runners with tight calves often prefer. Fit-wise, the toebox measures 90mm — medium-width, comfortable for most foot shapes — and the upper comes in a standard width. True to size. Allow 1cm growth room. The removable insole makes it compatible with custom orthotics. It is designed for active kids, sport, school pe, value seekers, and performs less well for racing or adult use.
