Parley’s speciality is creating sustainable and upcycled fabric from ocean plastic waste, and it looks great on a trainer. Ever since the original Parley Ultra Boost launched in 2017 the collaborations have been high in demand, and this blacked-out 4D rendition looks to be one of the best yet. The woven upper showcases signature blue strands, while branding is kept to a minimum with just embroidery at the tongue.
The 4D sole takes pride of place beneath the feet, also appearing in a stealthy black colourway. While the technology looks awesome, it’s also one of the most comfortable options on the market.
