740N Mushroom
740N Mushroom
Overview
The 740N Mushroom brings a refined, understated perspective to the retro-running aesthetic. Rooted in early-2000s performance design, the silhouette is reworked through a carefully balanced palette of warm neutrals and subtle contrasting accents, creating a sneaker that feels both archival and distinctly contemporary.
Its streamlined profile, layered construction, and muted tones make it an effortless everyday option. Minimal yet distinctive, the 740N transitions naturally between relaxed streetwear, denim, tailored casual looks, and neutral wardrobe essentials.

Design & Technology
The 740N combines the technical language of turn-of-the-century running footwear with the restrained design approach associated with JJJJound. Breathable mesh forms the foundation of the upper, while translucent synthetic overlays introduce structure, dimension, and a distinctly retro-tech appearance.
Underfoot, ABZORB cushioning helps absorb impact through a combination of cushioning and compression resistance, delivering comfortable support for everyday wear. The warm Mushroom-inspired palette is complemented by deeper contrasting accents, giving the silhouette depth without compromising its clean, understated character.
Fit & Sizing
The 740N features a traditional lace-up construction that allows for a secure and adjustable fit. We recommend choosing your usual sneaker size for the intended fit.
If you prefer additional room or typically wear thicker socks, consider sizing up by half a size.
Care Instructions
Remove loose dust and dirt with a soft brush or microfiber cloth. For deeper cleaning, gently spot-clean the mesh and synthetic overlays using mild soap and cold water, taking extra care around branded and translucent details.
Avoid machine washing, harsh chemicals, or excessive soaking. Allow the sneakers to air dry naturally away from direct heat or prolonged sunlight to help preserve their shape, materials, and finish.
