What boots and grip socks does Lionel Messi use?
Boots
adidas F50 Speed

The GOAT of football, Lionel Messi, has recently been wearing the adidas F50 Speed line of boot, which succeeded the F50 X line of boot.
These boots were engineered for speed, and developed by Messi himself to suit players who want to play similarly to him, if they even deem that to be humanly possible. Featuring a synthetic tongue for lightweight movements, players truly feel the weight of the ball to have full control over its movements.
Grip Socks
TRUSOX Mid-Calf Grip Sock

Messi has recently been spotted wearing the TRUSOX mid-calf cushion grip sock to improve traction inside his cleats.
These socks are designed to increase stability and agility, whilst letting the player remain confident and comfortable ingame.
