Circle Supernatural running show with thermoplastic elastomer (TPE-TPA) foam midsole made with Arkema Pebx Rnew, a partially bio-based elastomer. The knitted textile upper is placed in the mould along with the durable TPE outer sole, and over-moulded with TPE using Mucell physical foam technology. This creates a lightweight and durable shoe with excellent rebound and recovery.
Bridgedale Trekker sock, circular knitted wool blended with polyamide (PA), nylon and polypropylene (PP) for added wear resistance and strength, and thermoplastic polyurethane (TPU), spandex, for comfort.
