Does anybody else have separate ‘sock wardrobes’ for summer and winter? As someone whose feet both freeze and overheat quite easily, I definitely do.
One thing I find with superwash sock yarn, is that it doesn’t actually keep me warm - which works to my advantage in hot weather. My summer socks are therefore fingering-weight, superwash, and often lacy. I wear the lace ones on especially warm and humid days, and they are great for ventilation. Yarn with some ramie or silk content can feel cool and refreshing as well.
In the colder months however, wearing socks made out of superwash yarn, or any fibre other than wool, feels as if I have no socks on at all. I need woolly-wool. At least sport weight. But ideally DK, or even Aran. In fact, from October through April my feet mostly live in heavy Donegal tweed. I currently have 3 pairs on rotation and they are the ones that tend to get worn, while finer socks only come out when I need to wear footwear into which the thicker ones won’t fit.
Of course there are also the crossover socks. Fingering-weight, non superwash yarns work well on cooler summer days and milder winter days. These stay in rotation year-round, and always remain in my sock drawer.
Keeping my socks seasonally separated has actually been quite nice. The ones currently in season live in my sock drawer, while the off-season socks get put away in a separate box. When the seasons change, the socks rotate, and it makes or a fun ritual. It also makes me appreciate the sheer variety of fibre content and yarn weight available to us knitters these days. I have not worn commercially made socks in over two years, and absolutely do not miss them.
