This product is excellent, this is the second time i purchase this product, and my prior purchase was satisfactory as well, having to change it only because they worn off about 3 yrs after use. I'm an engineer and this is my footwear of choice, well designed, light on it's feel, and very rough on all sides! Complies with OSHA and all safety requirements my job demands. Will definetively purchase again once the are worn again.
