These were a mid 00's variation of Atomic's core new binding series, the Neox. When new, these retailed for over $1,000. The EBM, Electronic Binding Management, was a not only a left binding specific design but also fore/aft because the toe and heel worked together. The pair that is now in my collection is in need of a charge so if anyone knows a shop that sold these or knows of a rep that might have a charger, I would be greatly appreciative for the hook up.
