Yep, my boots aren't very good for walking either. The material is not very flexible.
My horse riding boots would fit a Harley-style, they are like classical cowboy boots. But I don't think they would protect my feet as well as those motorcycle boots since they have no ankle covers and they are made of softer leather. (And they wouldn't look as good... *insert a smiley holding a plate
I'm stupid*
)
But those Alpinestar-boots are something to think of. Xmas is right here, isn't it...
