On LightSpray™ Tour Boston

On takes over 660 Beacon Street for a six-day Boston Marathon pop-up built around its LightSpray™ upper technology — a sprayed-on, 205g construction worn by some of the world's fastest road racers. Expect a showroom-style experience with the LightSpray robot on display and the chance to try the LightSpray Cloudmonster 3 Hyper and Cloudboom Strike on-foot.

Around the Tour, On has programmed six events across the week to help runners land in Boston, race well and celebrate afterwards: a LightSpray demo run on the 18th, a skip-the-expo race-kit drop at the Newbury store, a marathon-morning-minus-one shakeout with DICK's House of Sport on the 19th, a finish-line "Flower Up" on the 20th, and two Post-Marathon Portrait sessions on the 21st (at the Tour and the Newbury store).
