I've got a few sets of cheap (low-cost supermarket) and moderately-expensive thermals. They're not marketed or branded for sport etc. but both are equally excellent. The more expensive set is thinner and feels just as effective, but is more comfortable (ease of movement) on days when I am outside and more active. With a set of thin, long socks worn over the thermal layer's lower legs, and thicker long socks on top, my feet are nice and warm if I'm sedentary or active for the day.
