Footwear in sports has evolved to a point where the athlete is wearing incredible technology to perform at ever higher levels, and the price tag on those boots is reflected in the tech. However, inside the boot the less glamorous insole- the main point of contact between the foot and the cleat- remains the same. The grip insole with moulded heel cup positively connects the wearers foot to the footbed, so all of that technology is not lost in the interface of foot and boot.
