This block is designed for new and humid snow. It covers temperature range between 0°C and -6°C. On old snow it is the best at lower temperatures -2°C... -8°C.
This is the block which helped to win several podiums at the last decade World Cup races during snowfall. The main feature of this block is that it do not show the best glide at the beginning but getting more and more slippery with each covered km.
