In reply to kevin stephens:
You're not alone! I've spent 15mins on icy traverses trying to get back into Dynafiddles.
With practice it will come, but it's worth marking the midpoint of the inserts with a perm marker on the top of the boot so you can see it from above.
Some find it easier to get one insert in first and roll the foot down to the other, this never worked well for me, I found it better to match both up and step in.
(I eventually switched to G3 Ions which are much easier, not to put you off though, most seem to eventually get it.)
