After beeing bored from long flat or small slope parts of splitboard tours, we have developed locking heel device compatible with SPARKS Blaze and Burner bindings (with a small change aplicable to Voile slidertrack as well). This improvement enables me to keep up with guys on skis, when in the ski mode. If you are interested, please check out the details on http://climbandsplitboard.cz/en/product/Auriga/ , for availability, do not hesitate to contact me.
See you on the top.
