I'd like to frame challenge a little bit and ask: what specifically is your goal here? Why do you want to wear the leggings? Is it about keeping warm while exercising outside in winter? Do you just like how they feel and/or look? Are you exercising or cycling for transport?

Personally, when cycling for exercise in winter* I put on my usual short cycling knicks or bib-knicks, and then over that I put long leg socks designed for cycling. Unlike tights, leg socks don't interact with your waist and hip at all—that's left to your normal clothes. They're cut to smoothly allow you knee to bend, and they are long enough for the top to cover your knicks and he bottom to be covered by your (foot) socks. I also wear arm socks, which do much the same over the elbow. It's also possible to buy long knicks if that's preferable.

When cycling for transport in summer I often wear cycling gear and get changed at my destination. In winter I'm much more likely to dress for the destination. I wrap a hair scrunchie around my right leg to keep my pants' material from getting dirtied and cut by my chainring.

For running, where I live just normal running shorts work fine in winter as long as I do a really good warm up. But I imagine the leg socks could be helpful here too.

/* Though I live somewhere quite warm. A cold winter's night might, at the most extreme, reach as low as 6 ℃. But it's far more typical for the night to not drop below 10°, and for the day, even the early morning, to be 14–18°. So exactly how applicable my experiences are to where you live is unclear.
