So I was in JJB today and was checking out the T90's and noticed that Shoots, Strikes and Lasers in black all seem to be made of leather whereas only the Lasers in white being made of leather, with the white Shoots and Strikes being made from that plastic-type material, am I right or wrong?

which white ones? the white black ones are plastic while the white gold ones are leather. Shoots are never made of leather. Strikes are made of calf while lasers are made of kangaroo leather.

shoots should be synthetic leather usually. the higher end stuff is usually made of proper full grain leather or kangaroo leather (not sure if they have lasers in k-leather.)?

lasers are k leather according to soccer.com and PDS
