I used to love Vivobarefoot shoes but they have changed manufacturer and now use different lasts for the men's & women's sizing. Which is a pain as the women's shoes are now too narrow for me and the men's shoes start at size 7 which is a bit too big.
I have a couple of pairs of Xero trainers but they have just decided to stop producing men's sizes below size 7.
At this rate I will be swapping from barefoot shoes to just plain barefoot....
