Labelled as EU 41 L (Ladies). Vivobarefoot size guides equate this to a UK 8, but as with all vivobarefoot shoes, they are designed to be roomy. They would comfortably fit a Women's UK 7.5 to 8, or a Men's UK 7 with a narrower foot.
These are practically new, however left shoe has some discolouration to rubber. see tread, insole and stickers - they've literally just been tried on and left in the cupboard!
usually ship same day any questions please shout 😀
