I've been working in the kitchen for almost a decade which means I've tried a lot of anti slip mats! There's always such a delicate balance with these shoes: • How effective are they? • How durable are they? • How comfortable are you? I am happy to say that they perform great in all three criteria! These are my everyday work shoes and I am very happy with them. I never feel in danger of slipping or losing traction. Having tested it with a few "worst case" spills just for myself, I'm impressed. Every part of the shoe has a strong grip, from the laces to the sole, this is the part of the work shoe that I consistently miss. Most non-slip materials will start to tear at the seams after a few weeks, but this pair is still fully covered! These shoes are comfortable and I can stand in them for quite a while, but after a week I definitely feel an increase in pain in the heel where I see more support from the shoe. grips tight like one of my favorite pairs made of non-slip material.
