The original intent of the adidas Predator design, conceptualized by the former Aussie footballing great Craig Johnston (who I've never heard of) was to give an increase to the friction between boot and ball via rubber patches or strips placed on top of the shoe. This increased friction, in theory would give an athlete greater control over the spin they were able to put on the ball...bend it like Beckham joke...whatever.
The latest in the Predator soccer shoe lineup, the Tango stays pretty much true to the original intent with what adidas calls a "Controlskin" upper. Joining the "Controlskin" is adidas' signature responsive Boost cushioning, a molded heel providing for a snug fit and instinctive movement. And, perhaps most noticeable with the Predator Tango 18+ Indoor design is the "Purecut" laceless sock forefoot with no edges, overlays or, most importantly laces. This is an adaptive, engineered "Sockfit" collar that expands to support your foot with every move. That's a lot of made up words adidas marketing department.
Now let's just consider this for a second. These kicks are meant for indoor soccer, but they look like a pretty sweet everyday walking around shoe to me. Anything I can slip on, not have to bend over and tie the laces while worrying if the bunny ears or bows or whatever song you use are the exact same length, double knot, tuck into your sock, whatever your obsession is...you can just slip these on. And apparently, they're tight enough to play soccer in without laces which seems good enough for walking my dog in. I'll let you know.
