These boots are sturdy, I can work about 4 hours in these. Great traction. Very rigid in the footbed. While the Vioz fit me perfectly, these abraise both my pinkey and big toe where the side of the boot meets my ultra high insole. (Any lower insole chafes my toes almost instantly). Im using thick SofSole with 2 thinner insoles underneath.<br />I have worked many half days in this boot, in attempt to break them in.to no avail. I limp back to the truck after 4-6 hours.<br />I believe eventually, these boots will get broken in, in perhaps 10-20 additional half days at work. Until then...<br />Not remotely like a Vioz fit, beware.
