Hi Magick.
How about these :
Bike Gear For Girls - Products - Boots
Although they may be too expensive for what you want.
You could also try tro get to the NEC Bike Show starting
on Nov 24th to Dec 2nd.
See if you can pick up a bargain.
The main problem is what style of boot are you after.
I just wear a pair of cowboy boots on both my FXSTC 1340
and my CBR 1000.
