I've bought a pair of Upz boots, the black ones.
Since I heard rumors about the softness of such boots, I would like to say that I tried to wear the red ones and they are really soft.
But the black ones are... really stiff.
They seems to be really great, having all the features a rider need.
Spring for heelside and backside, FIVE (adjustable) buckles+powerstrep, "walk" position, canting...
I found the feeling with them from the first day of riding.
