Sportflex Super X 720 K35 is the ideal surface for track and field beginners because it guarantees maximum safety and balanced comfort levels. Schools and other facilities for amateur athletes need comfortable, safe surfaces that are suited to track and field novices and for those practicing or training at school or for pleasure. That’s why MONDO designed Sportflex Super X 720 K35. It guarantees 35% shock absorption, which is 10% more than the Sportflex Super X (same thickness variant). Sportflex Super X 720 K35’s uniform 10,5 mm thickness permits the use of spikes up to 9 mm (6 mm compression spikes are recommended), and it can be installed in the central part of facilities for multisport surfaces and team competitions. Sportflex Super X 720 K35 is also suitable, as an alternative to Sportflex Super X 720 K39, for those portions of indoor athletic facilities that sit over a permanent, portable or removable steel/plywood structure, as those areas benefit from the sprung effect supplied by the structure underneath.
