Really quick and easy delivery, now I can finally find boots to fit my slim legs. Love the quality of the sizer, and the fact I’m earning rewards
Fantastic! My calves are smaller than a lot of people so I found it difficult to find boots that were snug until I came across Duo. I have owned my Duo boots for over a decade and they have lasted me very well. I don’t live in the UK anymore (in fact I now live somewhere warmer) but will definitely visit soon.
Fantastic idea! No more worrying if I have picked the correct size boot
I think this is a fantastic idea. I am unclear as yet as to what my size is in your boots as I have sadly just had to return some boots being too big. I have been in correspondence with customer services and have been made aware that there is allowance made for jeans so as not to have such a snug fit. I'm sure I will get to the bottom of it soon and be on my way to strutting around in my very own pair of duo boots soon.
Very good, unfortunately the boots were too big
