From quick lunchtime miles to your next 10K race, the new Ultraboost 23 is a responsive ride perfect for city runners. Infusing high performance with typical Stella McCartney style, these trainers are perfect for when those morning runs turn into lazy brunches with friends. Set on the lightest BOOST sole ever, they are supportive and designed to return even more energy with every step. The sock-like PRIMEKNIT upper is engineered with mesh inserts for a breezy feel, and there is a reflective cage-like upper to keep you safe in the dark. The ombre leopard print soles will give you some extra style points, whilst the recycled materials used in these trainers means that they don't just look good, but do good also. 

Designed in collaboration with Stella McCartney
