Asos mid calf boots

Definitely not made for walking, but I adore these boots. Been looking for some basic, yet not boring, black heeled boots. Ordered them @ Asos (thanks to Danielle), but unfortunately they aren't as comfortable as I wished for. They tend to run a size smaller, so I'm glad I did order a bigger size than I usually do. Maybe I just have to grow accustomed to them. Sounds like a whole lot of complaints.. I still love them :) What do you think?
