I was given these as a christmas gift and I love, love, love them!  So comfortable.  I have worn to work several times and even all day shopping and not had any foot pain.

The person sized up and I have tons of toe room.  They run a little narrow, more than short.  The leg shaft is narrow too.  I have a lot of problems with finding tall boots that fit, but these do work for me, even under jeans, so I think it depends upon your calf and where it gets wide.  I measured about a 13 1/2 opening at the very top.
