Traveling to Yunnan with my girlfriend and taking a long-distance bus, my girlfriend's feet are swollen. Any good ideas?

This is the edema caused by lack of exercise and poor blood circulation in the car. Travel a lot and give you some advice on taking a long-distance bus:

Try to wear soft cloth shoes or casual shoes. I prepare a pair of slippers myself, or I can prepare shoes of a larger size.

Insoles must be soft, breathable and soft. I usually replace the insoles that come with my shoes and add a pair of insoles made of Osolais.

Don't sit all the time, get off at the stop or rest point and walk more.

Soak your feet at night to promote blood circulation.

hope this helps
