@Linda thanks for reaching out! It's really difficult, over the internet, to say if the shoes you are considering will fit - sounds like you have a few very specific needs that really require a good fit! A few specifics about your questions above:
- Here are the women's Altra shoes we carry - our sale items have a reduced price marked in red
- Yes, if you order a pair and they do not fit, you can return them. Here's a link to our Satisfaction Guarantee
- Because shoe fit is so important, and very personal, we would recommend setting up an outfitting appointment at your local REI
Hope this helps a bit! If you need more information about a specific pair of shoes on our website, you could contact our Customer Support team at 1-800-426-4840. Also, we have removed your phone number and email address from your post to help protect your privacy.
