Minimalist Shoes, 1915

Screen Shot 2015-07-09 at 9.14.44 AM

In light of Erik’s continuing struggle with plantar fasciitis, and my own neverending search for shoes which fit my monkey feet, we found this 1915 handbook on military footwear, The Soldier’s Foot and the Military Shoe, by Edward Lyman Munson, a fascinating read.

Seems that way back in 1915 we knew that arch support created weak arches, and that thick soles impaired foot dynamics.

The principle message of this book is that if you want your soldiers to able to march long distances, and arrive at their destination in any shape to fight, you have to give them flexible boots which do not squash the toes or impede the natural movement of the foot. Simple as that.

So why, exactly 100 years later, are we still debating whether the foot needs lots of external support and cushioning? Why are overbuilt athletic shoes and supportive inserts still favored by mainstream opinion?

Minimal footwear enthusiasts may find the language below eerily familiar.

You can read the whole book at the invaluable archive.org.

(o) The shoe should not support the arch of the foot in the sense of lifting it up or buttressing it from below. This fact is opposed to common belief, but the latter is based on lack of knowledge of the anatomy of the foot and misconception as to its function. Rigid support of this region weakens its intrinsic muscles by favoring their non-use, and thus tends to directly cause the condition of flat-footedness which it is attempted to avoid. Barefoot peoples have no such arch support and flat feet are practically unknown among them. . . . In the new shoe, the purpose is to have the leather accurately follow the outlines of the average soldier’s foot arch, but without compressing the sole muscles to such an extent that their function will be interfered with and their development and strengthening be impaired. Every structure of the foot concerned in marching should be left free to function to the best anatomical and mechanical advantage. For this reason, the new shoe has no metal shank as stiffening under the foot arch.

(p) The sole should be sufficiently thick to prevent injury by inequality in the ground. But if too thick, planter flexion of the foot is lost and dorsi flexion much reduced. The foot is thus reduced to the condition of a solid block, hinging at the ankle and simply furnishing a solid support for the leg. Moreover, with thick soles, the leveraging function of the great toe is interfered with…

Bird’s Nest

I’ve been wishing I would come across an abandoned bird’s nest for a while now. They’re just such marvels, so clever, so sweet–one of my favorite things in nature, and that’s saying a lot. I imagined how I’d display a nest if I had one, how I’d keep it safe from the cats.

Then, the other day I found this one sitting on the coffee table on our back patio.

Just sitting there, right in the middle of the table, as if someone put it there on purpose, all strange and gorgeous. I assumed Erik had found it. And since the table sits under our grape arbor, and a few grape skins were in the nest, I figured the nest had been up in the grape vines, and Erik had discovered it whilst up on the ladder, trying to defend our grapes from sundry critters.

Nope. Erik knew nothing of the nest.

Logic tells me it must have jiggled out of the vines on the arbor — perhaps a rat dislodged it?– and it happened to land face up on the center of the coffee table.

But my heart tells me that it was a present.

I’m particularly fond of this nest because it is made up from pruned materials from our yard. In fact, I think most of it was filched from the greens bin that I let sit on the back patio for far too long this spring.

I see bits of twine from our bean trellis in there, and some grasses which look familiar. That ferny stuff around the perimeter are clippings from this asparagus fern that I’ve been trying to eradicate for fifteen years. (At this point, I admire its persistence so much that I can only bow to it as a respected enemy.) The fern is beautiful in this nest. The soft fluff in the middle may have been sourced from a silk floss tree about a block away.

The grape skins in the nest are interesting. Could be that the birds were eating grapes, but I doubt it. Instead, I imagine a lazy mouse lounging in the nest, sucking on our grapes in luxury and spitting out the skins.

Or the skins may have fallen into the nest once it was already on the coffee table. There is, unfortunately, a rain of grape skins onto our patio every night, as we steadily lose our war with the nocturnal creatures for our grapes. But that is the subject of another post.

Anyone have any guesses about what kind of bird made this nest? The bowl is about 3 inches (7.5 cm) across.

ETA: I’ve been looking at this great page of bird nests–it’s heaven for the bird nest enthusiast. So many types of nests! Wee little eggs! Baby birds! One bird even made its nest in a sweatshirt hanging on a laundry line. (That’ll teach you to bring in your laundry promptly):

And as of now my uneducated guess is that it is the nest of a house finch.

So Cal Alert: Polyphagus Shot Hole Borer

Polyphagus Shot Hole Borer, from UC Riverside’s Eskalen Lab

Seems the greater LA area is ground zero for the introduction of yet another exotic beetle which is killing our our beautiful native oaks and sycamores, our landscape trees, even our beloved avocado trees.

The good news is that the fungal disease propagated by the beetle can be treated if detected early. You’ll need the services of a professional arborist, but the cost of treatment will likely be less than the cost of tearing out a mature tree.

Look at this link to UC Riverside’s Eskalen Lab. Here they have several PDFs on identifying and treating the disease. They also have a map showing the spread of the disease. Of course, these are only reported infections–it could be much more widely spread.

(Note: a separate invasion was recently detected in the commercial avocado groves of San Diego county, so folks further south should be on alert too.)
