I’m still fascinated by these things.

Here are a couple from recent shoe purchases. They are similar but not identical, which suggests that somebody is working on the design.

It’s amazing that they fabricate these boxes, apparently by the hundreds of thousands, out of cardboard no less, and with such precision that they don’t need glue, tape, or staples to stay together during shipping, at the store, or on the way home. and all for what must be negligible cost.

The Saucony pair, by the way, represents my first foray into “zero drop” shoes. Actually they have 4mm, compared to the 10-12 on my regular shoes. I’ve been running for about 40 years, so it’s with some trepidation that I’m trying them, but they do seem to be all the rage.
