I would love to get you some help with the boots, but I’m not sure how much help I can be over the Internet.

I highly recommend scheduling an Personal Outfitting Appointment with your local REI and requesting an expert boot fitter. That way you can try on some different brands to see how they fit your feet specifically.

There are several different options available and I’m sure there's a perfect boot for you. Hope this helps with the search! Happy Hiking!
