Puma's soccer training shoes, the "Future Z 4.1 TT." The colors are neon yellow and black. "TT" is short for turf training, and they are suitable for use on artificial turf and hard ground. The upper features the "FUZIONFIT+" compression band for an enhanced fit. The outsole has studs arranged for multi-directional grip. I've used them on grass about three times, but the size didn't fit, so I'm putting them up for sale. Thank you for looking.
