I would buy these boots immediately If only I could figure out the f*ing size chart ???? I am a size 7.5 women's US - Any idea which cryptic size code I should select? When selling a product - Amazon / Blundstone - you shouldn't make it a struggle for someone to buy it. I don't want to waste my time guessing at the size when I'm ordering it - just to have to send it back when it doesn't fit.
