BlundstoneClassic Comfort 585 Unisex Adults' Ankle Boots

Q: Is this Australian sizing or is sizing?

Blundstone uses AU Australian sizes. I am a 13.5 but the AU 12 fits me perfectly.

Q: How slip resistant are these? Ima chef i work 10 plus hours in an environment with !ots of spills. Looking for a comfortable boot i wont skate around

I am also a chef and have worn Blunnies for years. Won't wear anything else. Heat resistant, slip resistant, chemical resistant. Really take good care of your feet

Q: What's the difference between the 558 & the 510?

The 558 have the tan leather lining that you see in the pictures. The 510's do not have the leather lining. I think the 558's are a little easier to put on because of the lining and less wear on you socks, but both are great.
