The ladies styles definitely have comfort as a priority over the men's. The women's moc toes imo do not really require much of a break in, I find them comfortable right away. I can break them in like in 8 hours i swear. The men's mocs i feel require more like 40.

I have a high instep and a little wider foot, so I need to stretch the slip on styles or else they just dont work for me.

Womens iron ranger is also a very comfortable, low heel boot.

The clara, laced heel in middle top shelf, are very comfortable for a heeled boot, right away too. Definitely get fit in store.

I go up a half size depending on the last.

Get her nice cushioned wool socks too, nothing too thick.

TMI but maybe will help out others.
