Nobull Sneakers Complete Buyer's Guide: Sizing, Models, and Best Workouts
Finding your correct size requires understanding NOBULL's internal geometry. The standard Outwork Trainer fits true-to-size for individuals with narrow to medium D-width feet. However, the one-piece SuperFabric upper does not give or stretch over time like conventional leather or flyknit yarn. If your toes brush against the front bumper out of the box, they will still hit that bumper six months later.
Athletes with wide feet (E-width and above) should consistently size up by a half size. That extra margin prevents lateral rubbing on the fifth metatarsal during heavy lateral cutting or broad jump landings. If your training regimen relies on thick merino wool socks or supportive athletic insoles, factor in an extra half size as well. For the Ripstop Runner, sizing runs closer to standard running shoes; order your normal sneaker size for short tempo runs, but step up a half size if you intend to log weekly mileage above 15 miles.
