"TEC-HRO pad" is a heel pad, which may be for new ISSF rules from 2013 used instead of the rubber trim on the shooting trousers!
This pad has non-slip properties and distributes the pressure of the shooting-shoe so that pain during kneeling shooting plays almost no role!
Pain free shooting favours the concentration and thus the performance of the shooter .TEC-HRO pad is made of very sturdy and durable special foam for long life! TEC-HRO chose a size of 18.0 x 18.0 cm and a thickness of 1.2 cm which the test of the instrument give exactly 1.0 cm!
