Adizero Adios Boost 4

From adidas

Designed and developed by Japanese master shoemaker Omori, the Adios is worn by elite athletes all over the world. The highly responsive cushioning returns energy with every step and the lock-down fit is perfect for racing and fast training sessions. It has a ultra-lightweight upper that is extremely breathable so you'll hardly know you're wearing them and the ADIWEAR™ outsole has great durability and grip in wet conditions. Adidas recommend going half a size bigger due to the snug fit.

It's normal for your feet to swell slightly when running, especially over longer distances. We recommend ensuring your running shoes have enough room to account for this and to allow your toes to spread comfortably, by leaving approximately a thumbs width of space between the end of your longest toe and the front tip of the shoe. This will help to reduce the risk of bruised toenails, blisters or numbness.

Running shoe sizes can vary slightly from brand to brand but we generally advise wearing at least half a size bigger than your regular shoe size.
