I really would need to see what you are describing. One consideration is due to standing, the veins become weakened and leaky. The brownish pigmentation can be related to what is known as stasis dermatitis. There also can be other conditions, some hereditary that can look like this.
If you notice any irritation or pain, then I suggest you see you doctor.
