I'm thinking of getting a pair of Frye boots. Specifically I'm looking for a 14"-16" shaft plus 2.5"-3" heel. There are so many I like -- Catherine, Nora, Tina, maybe Carmen. Do any of you have these boots? What do you think? I'm a bit concerned that a pull up boot won't fit over jeans and that a zip may be easier. I would love to hear any comments!!! TIA!
