For winter shoes I'd been wearing a pair of really crappy Shimano MT31 that's a size too large, with two pairs of wool socks and wind covers. I recently replaced my toe-only wind covers with full-boot style wind/rain covers. It occurred to me this morning that perhaps they'd be sufficient to allow me to wear my much better M076 shoes that fit correctly and are so much nicer in every way... sure 'nuff, that did the trick. Those shoes are also much easier to get those particular covers on, so the net time savings every time I put them on is greater than the time spent typing all these overly long sentences.
So that change right there made for a nice commute this morning. It's the little things in life.
