“The current Tibet seems a little narrower than the version I purchased 7 years ago (it may also be that they will stretch a bit).There is also a small change to the rand which is now two pieces rather than continuous, which seems to be a drop in quality. Otherwise a great boot. I was very pleased with the comfort of my first pair. The air pockets in sole/heel help with cushioning but may be less long-lived than a more solid compound sole - I tore a hole in my last pair, but am prepared to sacrifice indestructibility for a bit more comfort.”
