Hey Ernie,In terms of sizing you should go with a 10. Their sizing is right on but they leave some wiggle room for thicker socks etc. As far as the money, jump on "live chat" and ask those folks. They'll be able to give you the most accurate information and instructions. They're great to work with so you'll be well taken care of!In my experience Sorrels run very generous (wide and high volume). Also, the way they fit is a little looser so they are pretty easy to slip on. If they aren't laced really tight the boots will slip off when you step into 10+ inches of powder. and will almost slip off in powder. If you get these wear heavy socks and add a Winter Green Superfeet to your order. Also, look at models that allow you lace further down the toe and can be laced tighter. I've attached a pic showing the insole of a Sorel compared to a casual shoe.Mahalo, Sumo
