I garden in these:

It isn't, however, terribly comfortable to do a LOT of digging in these. Digging a hole for a tree or two in soft ground--no problem! Digging in hard ground is painful with my shovel, so I switch to other shoes for that.
Soft star also has a lot of other minamalist shoes, too, and some that are taller. I haven't tried these ones, though:
As well as ones that look like "normal" shoes.

Speaking of makiong you own boots, I funded this kickstarter last winter to get the shoe tutorial for my sister-in-law. It's a really in-depth, beautiful, and fantastic tutorial. They're in the process of releasing a video for making your own work boots.
