Well, resoling is much cheaper than getting new shoes, the last time I did it in the California it was about $25. If worse came to worse you could buy some shoe goo and try to repair it yourself. Ah, well that is the cheapest thing I can think to do, it's better to repair a good fitting pair of boots than get a new pair. You can always check the Goodwill in the men and boy's section. A ladies 8 is a boy/man's size 6. They are also wider, some styles of men's short trouser boots look like boots from the 19th century.
Good luck,
