Another Minimalist Shoe Idea
I heard about some kind of shoe/slipper made by a company called Zemgear. http://www.zemgear.com/
They are less expensive than Vibrams, more expensive than water shoes. They come with different colored stripes, and they have a high ankle model. I got a low ankle pair and tried them out. Fantastic for cold weather running! I chose black on black. My wife calls them my duck feet for some reason.
Easy to put on, easy to take off, fit is superb, feel is great, extremely light weight, nicely warm, and I can easily stuff them into a fanny pack without feeling like I'm lugging a bowling ball around. I really like how they hug the arches of my feet. Their design is so simple, I believe I could replace the sole myself if it wears out. In fact, by turning them inside out, it would be easy to duplicate the size and shape of each component part and just make me some new ones out of any material I choose. I think I would like fleece; or maybe felted wool.
My only problem with them is they soak up moisture like a towel. Not good for wet weather running. This means not good for about 80% of my runs up here in the northwest! But considering I only got them for running during the most extreme frigid weather, they should work out just fine. We only get a few days of truly frosty, sub-freezing weather here. I can run in everything else without any foot coverings. I'm not sure how they would do on icy surfaces yet.
Happy running to you - in any temperature!
