2017 UPDATE! I purchased these boots earlier this year and made them work. Click here to find out how.
Last month I posted about these amazing boots that Dainese created just for women. Race level boots with full lateral, ankle support. Something my Sidis just don't offer. :-(
I tried on the Dainese boots in 37 (my size when shoes run tight) and they're just TOO NARROW! *Cry* I couldn't get my amazing insoles to fit either, even a size up. The good news is, if you do have a slimmer instep, you will LOVE these. They also have a speedlace system, which allows you to cinch the ankles down even more! (Oh how I already envy you!)
This photo is from the back of the boot, all Dainese Race style boots are rear-entry. They also have velcro adjustments on either side of the boots (red circles) so you can adjust your calf fit, depending on what kind of pants/race suit you're wearing, or general calf size.
I wasn't trying to put the entire thing in side (all three pieces together). I could barely get my foot in as is. I have a high instep, so a lot of shoes in my size (6.5 US) are small at the opening so I can't get my foot in.
