Hey David, I'm up here in Bossier. I'm not knocking the guys at the local Tandy, but I'm not sure it would be worth the 2 hour drive.
Now, if you are planning to make a decent sized purchase and take a class then it may be. The folks there are real nice.
I have wanted to do boots and shoes myself, but it seems that information isn't so readily available. Now there is a group called The Honorable Cordwainers something-rether that does have a significant source of information to dig thru. I think you can find them by searching H.C.C.
They are all about preservation of the knowledge. I think I read on there or maybe in a book that the knowledge of lasting has been lost twice already in human history.
That seems even more hard to learn about than shoemaking. And yes there are a few places to buy a pair of lasts. However knowing which ones to buy seems to be difficult to find out.
If you can make it up this way, I have a few chunks of granite I can send back with you.
