ON – race and train, the latest innovations in running shoes

Footwear manufacturer ON has unveiled the LightSpray Cloudboom Strike 2, an elite racing model crafted for half-marathons and full marathons. Constructed with an automated technique that rapidly sprays a continuous strand directly over the mold, the seamless upper discards traditional stitching, panels, overlays, standard tongues, and ordinary lacing, yielding a lightweight shoe registering at a mere 158 grams.

This streamlined build minimizes waste and lowers production carbon emissions while acting like a second layer of skin to prevent friction zones, packaged alongside an Elite Run Sock High Hyper to optimize fit. For runners who still crave a more customary engineered mesh upper with greater adjustability, ON provides a standard iteration as well.

Targeting a market where high-end race equipment typically exceeds £250, the shoe overhauls previous brand hallmarks that were frequently critiqued for being overly firm. The sole integrates updated CloudTec Sphere shaping alongside Helion HF supercritical foam and a revised arched carbon Speedboard, providing enhanced impact absorption, softer bounce, and reliable steadiness despite the sparse upper materials.
