Certain athletes talk a good game. However, the best ones can feel it. Enhance your play in Copa Sense by connecting with your senses. We built these adidas firm ground football boots from the inside out to achieve the best fit possible. Stretchy adidas Primeknit and K-leather are combined in the lace upper. The negative space of the foot is filled with foam pods at the heel, creating a secure bond between the boot and the body. When you make contact with the outsole, the two medial studs bend, providing a comfortable first touch.
