I also have the trackers. They are stiff-good advice on the alcohol thing-works great. The problem is if you have big feet (size 12+) The boots aren't low to the foot like astars are and are a bit cumbersom on the shift foot. The price is right though.

 

Oh by the end of a long day of riding I actually felt like I was gaining ground on the break in. In fact I only missed a shift twice. I am actually really starting to like the boots.

 

I have a new pair of Sidi Raptors. Fit good, great construction for the price, but I'll have to try the alcohol trick to break them in. They are so stiff, there's no way I can get my toe under the shifter to upshift or over the shifter to downshift.
