What boots and grip socks does Mo Salah use?
Boots
adidas F50 Elite (laced version)

Mo Salah is currently an Adidas athlete, and has chosen to adopt the F50 Elites as his chosen boot as of recently. They have served him well, as Salah has been one of the best players in the world since 2018.
The F50 Elites possess a lightweight, thin sythentic upper for speed and a Sprintframe 360 outsole. These boots are perfect for rapid wingers and strikers who use a burst of pace to get round their man and to make piercing runs behind the defence.
Grip Socks
Pure Grip Socks Elite

Mo Salah has recently been using the Pure Grip Socks Elite, a more expensive sock designed for professional athletes. It is likely they were designed and sent to him specifically in partnership with either Liverpool or Nike to fit within the kit laws.
The Pure Grip Socks Elite series offer improved traction and stability to reduce slipping and blisters, perfect for players with quick feet who are constantly changing direction and operating at a faster level than their opponent.
