We haven't gotten to that point yet, I would imagine eventually I'll need to, but with the holiday coming up and all...
And it wasn't a "pro liner" persay, it was a "pro fit". I believe someone wrote about it a bit back who (if memory serves) was actually fitted directly at True. As explained to me, the difference between "pro fit" and the standard "retail fit" is that pro is meant to remove all negative space right from the get-go and and generally be a much tighter fit to your foot. Retail takes into consideration that it may not be everyone's cup of tea to have a second skin-esque skate, or might use thicker socks, looser tightening of laces, etc.
I opted for the standard black clarino liner over the moisture wicking, as they said the clarino is much more durable. Not sure if they even offer the tan clarino anymore, truth be told!
Overall, I know they want to address my heel lock at the factory as well as the extra length. However, I felt like they nailed down my forefoot pretty well. (I have stupidly wide forefeet with pretty narrow ankles) As a matter of fact, when we unboxed and the Pure hockey guys saw the build out of the forefoot on my boots, their response was "holy crap". A day in the life of having Hobbit feet, I guess...
