I've been contemplating the high cost of shipping heavy footwear (and clothing like robes or jackets) lately as well. I've come to two possible solutions that I can live with: 1.) Use the Cost Varies by Location feature and identify within my shipping narrative I am using this function because the item is heavy and the cost is so discrepant east coast v. west coast since I am shipping from NY, or 2.) Go with a standard shipping price with the self-understanding that I am making money off my east coast ships, and lose a few bucks with the west coast sales. I tend to ignore the sales where I make $3 on shipping shoes, but man I get my panties all up in a bunch when I lose $3. Last, but not least, on shoes that are not super expensive, and will not suffer from a bit of box cramming, I've received shoes jammed into a medium flat rate which is right around $11 for those with no additional shipping discounts.
