I've had these for a little over 2 years - probably 60 hours on them. OK for MX but too stiff for me in most off road situations;
PRO: They seem very protection in the foot area (the plastic is stiff all around the foot); fit is fairly true to size (I got an 11 for a 10.5 foot and it is roomy but not sloppy); buckles easy to adjust length; durable;
CON: Very stiff and mine have stayed stiff; can't feel the shift lever and brake pedal feel is very limited because the boot is so stiff; mine had WORST BUCKLES ever designed by man until modified; the buckles would not come out of the slot that they pivot in (screwdriver or pliers required); I had to hog out the slot where the buckle pivots into the fixed portion (drill bit slightly larger than the existing slot size); now the buckles are OK but the boot is so stiff, it'll only be used for the roughest of rides;
I used these through a whole season of adventure riding. I was beat to hell multiple times involving no less than 15 times being thrown off my bike or landing under it. The toe box is huge but once you have moved your shifting lever it actually allows a moderate amount of feel for shifting. walking in them makes you feel like an astronaut but the rigid souls allow for hours of standing riding. I got a 10.5 as I am a 10.5 and they are just barely usable due to tightness in the calf and upper foot so I wish I had a set of 11s. The only feature missing from this boot is some crush resistance around the ankle. There is some but I did get a bruise on my ankle on one of the offs. Durability wise They look dirty and broken in but I feel they will be good for another couple seasons. Extended knee pads fit into the top of the boots very well. These boots are worth every penny. Ride safe.
