Verified
Authenticated in-house
Every pair is inspected & verified by our team before it ships.
The Fresh Foam X Hierro Trek brings trail-ready sophistication to New Balance's outdoor footwear line. Built with a dual-tone slate grey and lone star grey palette, the shoe balances technical capability with understated aesthetic restraint, ideal for both serious terrain and everyday versatility.
Designed to handle variable conditions, this silhouette combines responsive cushioning with purposeful construction. The refined neutral colourway emphasises the shoe's structured form, making it a considered choice for those who prioritise functionality without compromise.
Every pair is brand new and unworn, supplied in its original box. Nothing we sell is used, worn or ex-display — just deadstock, ready to wear.
Every pair is verified 100% authentic in-house before it ships — checked against known-authentic references for materials, stitching, labelling and box details.
Fast UK tracked delivery, with next-day options at checkout. Orders are dispatched securely and double-boxed to protect the shoe box in transit.
