I have a set of Daleboots that are comfortable and ski great. The Intuitions that came with them are starting to pack out and I'm finding it necessary to tighten the buckles considerably more than before. After reading all the good things about Zip Fit, I'm considering trying a set, but have a couple of questions: First, will Zip Fits work with the Daleboot style of shell (and any particular model? It is barely a 15 mm shell fit)? Also, I live on the east coast and see no dealers listed near here, so would it be possible to order them from someone, and either install them myself, or go to a recommended fitter nearby for installation?
