These are "spider veins" or vericose veins. It is a genetic anomaly but doctors presume it has something to do beside hormones within the individual. You can't aid your genetics but spider vein are completely harmless if aesthetically pleasing.
If you want to get rid of them, within is a solution called sclerotherapy. They unsophisticatedly inject saline solution into your veins and it make them disappear.
to get blood to your foot! lol

If this is a purplish marbling, it is tremendously likely a condition call Livedo Reticulitis. This is most often associated beside an autoimmune disease. I have this on my legs arms and torso. Here is a interconnect with a photo.
