I have Solomon Impact 9 boots (26.5) and ever since I bought them about 2-3 years ago I have been trying to make adjustments for a high instep and a somewhat beefy calf. After about 30 -40 minutes, my left foot (in particular) gets tingly and begins to go numb to the point where I have to take the boot off or release all the buckles to let the blood flow again. I have just cut out a portion of the plastic top of the liner and it seems to help a little bit but not enough. I'm wondering if using an Intuition heat-moldable foot liner will help take the pressure off the spot(s) on my foot (especially the top) where blood needs to flow and maybe even my calf muscles that also have blood vessels that run down to the foot. Can anyone give me some advice?
