Ralph wrote a review of Marker Duke EPF Ski Binding on February 14, 2013
I returned my first pair to Marker after 10 days of side country use, due to excessive lateral heal movement in the tour mode.Marker replaced them under warranty. I now have 2 days use on my new pair and I am back in the same position. I can not fault the binding in ski mode, but I have zero trust in their durability in tour mode and therefor can not take it anywhere I can not boot pack out from.
I wish I had not brought these .
