For a simple, low tech way to make healthy functional foot coverings, I can recommend the 5 DVD set from http://www.healthyhandmadeshoes.com/
. I bought this even though I had made 3 pair of shoes by then, and still got a lot out of viewing it. This has a lot of good basic, easy to understand info and does not require either a lot of tools or a lot of materials and provides basic patterns.
I expanded on this outsewn technique by making my own lasts and patterns for more of a moccasin toe to get a higher toe box for my toes which curl up.
The problem with today's shoe designs is that they really destroy the functionality of the foot. Look at how the shape of your childrens' feet change as they start wearing shoes.
Shoes that distort the natural gait result in problems with hips and knees in later life. The Vibram five finger movement is an expression of this knowledge. However, they do not serve well in all situations and climates.
I am trying to design and make shoes that are faster to put on than the 5 fingers and better in rainy weather than they are.
I think making shoes is a lot easier than raising kids, but it does help to have good manual dexterity.
I would say to go to a Tandy store if you have one nearby and get a small project kit that requires sewing to see how you do with it. The one in Seattle is very helpful with answering questions and providing help. You can even buy a moccasin kit from them, just to get a feel for moccasins.
It is important I believe that you enjoy what you are doing. Otherwise, better to do what you enjoy and buy shoes, if you can find ones that fit!
