Sorry, a horribly bad picture, but I like these boots and right now, I can't take another one:
The boots are dark brown soft leather and have zippers on the inside. You can probably see the flat heels of 5cm only. I am not a fan of high-heels, this height is very good for my taste.
Culmor, I like your "perfect boot" too, except, as mentioned above, lower heels would be even more perfect for me. Unfortunately, this style always comes with extreme heels.
Eventually, I want to get rubber riding boots, but right now my budget is exhausted.
Now some slightly better pictures:
Same boots as above:
Short boots:
I like this style a lot. Unfortunately, these were available only 2 sizes smaller than I need, but slowly, they are getting wider. I can wear them for about 30 minutes now, without having real pain.
