So to answer my own question. Yes it works just fine as long as the slope up isn't terribly steep and you don't mind a couple of kick turns. Slapped the old skins on my Liberty skis with Look bindings, put my Scarpas in walk mode for the first time in 3 years and voila! Changed my avatar.Sold my tele skis and frame AT bindings last year thinking I was getting too old for uphill. Dang!
I still have the skins and a I have walk mode on my Scarpa boots. How crazy would it be to try to skin up in alpine bindings? Not steep and not a long way, one run for exercise and a lark. Somehow that sounds less horrid than snowshoeing with a pack and skis with boots in the bindings.
Course it was 1.5 hours up and 5 mins down. But the first 20 or so turns were freshies. The rest - where lots of folks had walked - were pretty tooth rattling... but still fun. Tons of people out with kiddos and dogs. A really nice few hours if happy place.
