This is the everyday trainer from Nike. I know Pegasus 35 with full-length air unit has been out for a while, and Pegasus Turbo was about to be released — which is why last year's model is on sale.
Colour: Grey, but it looks pretty much black to me. Sizes are US 7 to US 11.5.
95/100 review on RunRepeat. 9/10 review on RunningShoesGuru.
I think the 'grey' colour is for the Nike tick
