Heredity: We inherit the gene for weak vein walls, thus spider or varicose vein or weak vein valves, sometimes later in life after environmental or work issues affect us - like prolonged sitting, standing, heavy weight lifting, pregnancies, hot tubs, trauma to legs, hormones. Wearing medical support stockings, esp for work or airline travel and weight lifting and pregnancies can slow the progress.

UV or inherited: Some people hjave a tendency to develop spider veins. In addition, sun exposure may injure collagen and lead to spider veins. Occasionally spider vein may develop after trauma.

Heredity & hormones: Heredity and the hormones are the most likely causes. If you are taking a birth control pill, that can play a role as well. It probably doesn't have much to do with standing, inactivity, what shoes you wear, and your weight. Crossing your legs when you sit down doesn't play a role at all.

Heredity: Far and away, the major cause of varicose and spider veins is heredity. Other factors can contribute to their development if you have inherited a tendency to get varicose veins in the first place. These include prolonged standing, age, pregnancy, hormones, and trauma. Surprisingly, obesity has not been shown to be a cause of varicose veins. It does increase the risk of complications though.
