Thanks for reaching out!
The Alpina Alaska BC Cross Country Ski boots may be a great choice. In my experience, Alpina boots tend to work better for a lower volume foot, whereas Madshus and Rossignol tend to fit higher volume feet a little bit better. Since you don't live close to an REI store, we highly recommend scheduling a virtual outfitting appointment with one of our expert boot fitters. They can talk you through some options and make some suggestions based on talking with you about your needs.
Hopefully this helps, thanks!
