ALLBIRDS TREE DASHER

£120, allbirds.co.uk

Allbirds is the brand marrying performance with sustainability. Every shoe it produces uses as much natural material like wool, tree and sugar as possible, and the brand prides itself on being 100 per cent carbon neutral. Thankfully those eco credentials are backed up by impressive design, too, with the Tree Dasher boasting a dual-density SweetFoam® midsole for cushioning, stability and ample energy return. Elsewhere, the seamless one-piece upper – made from FSC® Certified eucalyptus trees – provides sock-like comfort whatever the workout.
