The Herculan SR 10+4 system consists of a special, soft, shock-absorbing underlayment which is provided with a very strong and elastic top layer with a wear-resistant, flexible coating. This combination makes the system very suitable for, in particular, indoor athletics, where spiked shoes are used. The high shock absorption provides comfort to the athlete which reduces the likelihood of injuries. If desired, this system can also be used for all kinds of other indoor sports.
Shock absorption (EN 14808, DIN 18032-2): 45%
