Firstly, this boot is as light as a feather and I wasn't expecting that at all as Im used to a traditional sole, whereas this isn't.
I struggle with shoes in general as Im a A-AA in width which is narrow and with narrow calves. This Habbot 42 fits me and im approx 27.7cm long and it is actually quite good in width for me, as the laces allow me to pull the boot in further.
My opinion is that if you are wider this boot probably won't fit and they would be snug around the lower calves as well. They need to be worn in a little at a time to allow the boot to relax and feel comfortable around your ankle. Im just happy that this boot fits me and I can imagine taking these travelling as they are lightweight. Ive rated it 4* as I will need to get a boot maker to add additional holes to the leather strap. Thanks Habbot.
