great, thanks for the tip.
On another note, just out of interest.
I've had my boots professionally fitted, custom footbed, heat moulded liner and shell - salomon XPro 120's.
I just tried them out for the first time at my local indoor centre. They feel great and seem a good fit. I only buckle the front two just to close the boot up, so there is very little pressure on the top of the foot. However, my big toe on my left foot seemed to get extremely cold at one point - to the point I felt I should take my boot off when I had lunch to let it warm back up. After this it did seem to be ok when I went back out for a couple of hours - it was -5c in there, should I be worried about it when I hit the mountain? Maybe I had around my ankle a buckled a little too tight the first time that was restricting some flow?
Also,I've read a couple of guides online that say you should buckle the top two up as tight as possible - if I did that, I feel it would be way too restrictive. I presume l should do it tight as I feel necessary, as long as my heel is secure and I have contact with the tongue at all times?
Any tips would be great!
