If this helps… my old PDG boots were 28.5 and they were very tight, so I went to a 29 for the new PDG’s - They are really big. I’m doing some work with our local BC boot fitter but it’s taking a lot of extra padding, foam. We fitted them virtually and I you gave me the opportunity to send them back. Is the newer model a larger dimension of the older model?
I've used the Dynafit PDG boot the last four seasons for ski-mountaineering racing, and finally decided to retire them and pick up the updated PDG 2. My immediate impression was that I love the additional toe box volume - the fit was comfortable out of the box, and I threw in a set of aftermarket footbeds to provide support and now the boots feel perfect. The overall design and style didn't change too much from the original PDG - I still love Dynafit's patented ski/walk throw mechanism, which makes transitioning a breeze. The full carbon cuff provides stiff lateral flex, and I feel confident when holding an edge at high speeds. The new Speed Nose does provide noticeable improvement when it comes to touring efficiency, as the toe-off when striding out is a bit snappier and quicker. Overall, awesome boots if you're looking to maximize uphill performance for fitness skinning or racining.
