I should have done this a while ago, but better late than never I suppose? :)
The SPADA Slipstreams are very comfy, warm, stylish and best of all really good value for money.
I paid about £70 for mine and they've kept my feet dry and warm in the recent weather.
They look good too.

On the down side, they are a little bit bulky and take some getting used to. When I say that what I mean is that it's difficult to feel if your on the gear shifter and brake at times.
I'm used to it now as I think they needed some breaking in. So be aware of this.
But these are my only boots and since I've been using them they've been trouble free.
