CSA
Meets Federal Motor Carrier Safety Administration requirements of Compliance, Safety and Accountability.

CSA stands for Compliance, Safety, Accountability. It is the safety compliance and enforcement program of the Federal Motor Carrier Safety Administration (FMCSA) that holds motor carriers and drivers accountable for their role in safety. CSA affects motor carriers, including owner-operators, by identifying those with safety problems to prioritize them for interventions such as warning letters and investigations. CSA affects drivers because their safety performance and compliance impact their safety records and, while working for a carrier, will impact their carrier’s safety record.

After 2 months of wearing, they squeak fart, LOUDLY, in the heel.
Finally found a well fitting boot that the safety toe doesn't rub the top of my toes, but the farty boots are poorly made.

I purchased these boots based on price, insulation value and style. I wore the boots and immediately found them to be extremely comfortable and light weight, no hassle with brake in period. I was thinking with the insulation value being dbl of most competitors I thought they would suite me well. As I live in Alberta Canada and the winters can be extreme I found immediately that these boots are not good at all in the cold weather. I’m a construction worker and do a lot of steel stairs and climbing on steel in my job. The sole on these boots turn as hard as a hockey puck and don’t stay pliable and makes it dangerous to do my job. Even walking on snow and ice is a challenge. I’m very disappointed with this part of the boot.

Great boot needs more cushion
A little on the heavy side and not much cushion. Spending more than 12 hours a day in these boots I had to purchase new insoles since they feel very rigid . But the sizing is perfect I bought one size smaller a 8.5 instead of a 9.
