You should have her go to ridegear.com and see what the average women's boot looks like so she knows what to get. On my husband's website www.thedynamiccycles.com he has a link direct to them! Hope it helps, if not go to your local gear shop they might have a good boot there! Good Luck!

You two could both check online what boots are available.

It really boils down to whether she is planning to ride her own bike, where she is riding the bike, and what features she wants. She can get boots that give decent ankle and calf protection, that provide enough insulation from both rain and cold, that lift her up an extra inch, that are all leather or part leather, with zippers and velcro or with buckles and velcro or all velcro. And she needs to try them on. I've found that men's boots are sized 1.5 sizes larger than women's sizes and they're also roomier in the box/ball of the foot area. If she's like most women, her heels are narrow so she'll want the boot that won't give her heel blisters if she has to walk in them. And Euro sizes definitely need to be fitted before buying, esp. if she is a half size.

I have four moto boots -- 2 casual, 1 for all-weather, and 1 for dirt/supermoto. The last two will protect my ankles and calves more than the first two, but they were also stiff when new.
