These boots are not comfortable at all, perhaps Ok for a Moto Cross run but if you are planning to go far, not so much. You can't walk in them, and changing gears is a cruel process for your gear lever as you have no real ankle movement.
For long days I prefer my Gaerne boots,(1000 miles off road in Patagonia) or even my eternal Hein Gericke boots (Tierra del Fuego and back) which I think were also made by Alpinestars.
So if you prioritize protection, don't mind walking like robocop, and spending ages softening them up, these are for you. For all other people there are better choices that are same or cheaper
These are great motocross boots. Provided you don't expect waterproof.
That is my only gripe with them. Other than that: great.
They were bought after my return from Argentina where a GS footpeg had tried to mate with my tibia. No broken skin, but bloody painful.
So after that I decided: biggest, strongest.
I hunted about and opted for the Aplinestars as, despite the acres of polycarbon armour, the felt like well padded socks: very comfy! They are also very warm.
In addition they are tought: they stopped my ankle getting crushed between the same GS and a crash barrier after a lady in a Fiesta felt I'd look better on the far side of the barrier. The boots survived remarkably well. The GS did not.
So if you want security and don't need your boots to blend in, get these and a few pairs of goretex socks and you'll be warm dry and safe!
