Ok, so I've had a set of Nordica Speedmachine boots- this is their 5th season and about 180 days of skiing. Coming into this year, I knew the liners were well past packed out, and at the beginning of this year bought a new takeout pair of Tecnica Demon liners to replace. Shell fit in the boots, I have about an index finger of room at the heel.
The liners did their job and made the boots feel like new again, and after the 1-2 days, the fit was spot on. DEFINITELY less space- with the original liners I could lift my heel and I could wiggle my toes a lot more.
However, I'm 7 days in and have some pretty good toe bang going on- deep bruises under the toenail and a blister on the front of one foot. I have NEVER had this before with these boots.
I am 99.9% sure these boots have less space in them with the liners, including in the toebox.
My understanding is that toe bang is usually caused by loose boots, but I don't think that is what is going on...
Could too little space coupled with impacts be causing the issue? I've been having some great powder days early season, but part of the caveat is that gullies and steep-to-flat stuff isn't filled in or packed to moderate the transition. I've had plenty of encounters with crossing surprise stream gullies where I am cranking back and getting slammed a bit coming back up the opposite bank, as well as steep-to flat transitions. I suspect I am slamming my toes a bit from this.
I don't feel any pain while skiing, which makes it tough to figure out when the problem is happening.
