• UK sizes are 2 lower than US sizes for women, and 1/2 a size lower for men. So a women's UK 4 is equivalent to a US 6.

  • Hi, you would want to contact STP. You can call them, do live chat etc. I only own a pair of these. I don't know what size you would need. I'm sorry! I can say they are great boots, though.

  • If you hover your mouse over or click on the sizes the corresponding numeric size will be displayed in US male and female sizes.
