Brand new women’s lightweight ankle boots from Xero Shoes. Thin, flexible sole with a sustainable vegan canvas upper and cosy lining. US size 10.5, equivalent to a women’s UK 8-8.5 depending on how much extra room you like in boots. The internal insole is 27.5cm long, and 9cm wide (they’re also suitable for wider feet as the upper is soft - e.g. my feet are 10cm wide and I could wear them comfortably). There is an adjustment strap which you can tighten, I think it is designed to keep the shoe on more securely if you need it. I wasn’t able to test it properly as they’re too big for me (I bought based on the EU size, which is wrongly converted). Brand new in box.
