United KingdomSadly, whilst they looked perfect online, when they arrived, they were just too wide in the foot. The finish of the boot is good quality and as these are my third Duo boots, To be honest I would not shop anywhere else however I ended up driving to your pop up shop in Bath to try on some others. I do miss your London Shop!
United KingdomSadly, these boots catch on my ankle bone and were not suitable when I tried them on so I have returned for a full refund. The boots though were a lovely good quality and the calf size was perfect. Would have been perfect if not for the ankle bone issue, just not for myself personally.
United KingdomI bought these boots for my wife Christmas she absolutely loves them so comfortable and the great thing is they do a calf measurement before I bought these boots I went to jones the Bootmaker and there boots size measurements are very misleading but these boots from Duo are brilliant and they are very quick on their delivery bought one day here within 4 days. Regards Rod Conway
United KingdomThese are by far the best boots I’ve ever bought and great value for money
United StatesThese boots are beautiful. I love that as a wide calf girl, I can still wear a boot. Thank you Duo Boots!
