There are some reviews here:
As a female you might want to avoid ones that are known to run wide (e.g., Risto).
Masch, Debra, and myself got Do-Wins (regular - not women's).
I haven't used mine much (using a cheaper pair that I got the heel built up more on). They do feel much more comfortable than my cheaper pair, though. Debra and Masch seem to love them (there is a discussion earlier in my log about this - but I wouldn't recommend hunting through my verbosity to find it).
With sizing I think it depends a bit on how you wear your 'normal' shoes. I ordered 1 size down from my Chuck Taylor's and the things were too tight to get on my feet without them turning numb. I ended up with the same size as my Chucks - but realized in the move to vibrams that my 'normal' shoes are a bit on the tight round the toes side. IF you wear shoes fairly firm against your toes then DON'T order a size down (or I probably should just say that 4 people I know who have done this have needed to return them).
Because of the wood heel... I find the shoes a little uncomfy to stomp with... Like wearing fairly thick socks with them to soften them a little... Sizing is hard. A good returns policy is a virtue.
