Bring an understated, commanding appearance to your daily training loops, treadmill intervals, or multi-sport active rotation. The New Balance 411v3 “Castlerock Grey” edition swaps flashy patterns for a refined, monochromatic architectural profile. The deeply saturated castlerock grey mesh baseline is elegantly balanced by structural no-sew overlays, anchoring a clean athletic geometry that pairs seamlessly with technical track shorts, compression base layers, cuffed joggers, or casual weekend windbreakers.
Don’t let rising road heat or heavy pavement vibrations break your rhythm when your performance pace intensifies. Woven from a featherweight engineered textile mesh upper, this shoe allows fresh air to continuously sweep across your foot to eliminate heat build-up. Down below, the premium DynaSoft midsole architecture pairs ultra-responsive performance with a plush underfoot feel, converting downward pressure into snappy energy return while keeping the overall frame incredibly light and unburdened.
Ground-Contact EVA Outsole: Outfitted with an ultra-lightweight structural platform detailed with target rubber traction pods to maximize durability in high-wear zones.
No-Sew Overlays Shield: Built with lightweight, heat-sealed reinforcements around the lace track and toe box to eliminate internal seam rubbing and chafing. [
Plush Collar Padding: Features a generous amount of anatomical cushioning around the ankle collar to lock your heel firmly in place without pressure spikes.

Sizing Advice: Sourced from expert brand testing, the New Balance 411v3 features a streamlined Standard D Width profile layout that contours the foot true to length. Order your typical size. If you have wide feet or a high instep, the toe box can fit slightly snug; in those situations, we recommend opting for a half-size up.
