I have lots of women's footwear in size 5 or 5.5. Prices are as follows:
Black leather boots by Marc Fisher. Size 5 1/2. $30. In excellent condition. 3 1/2 inch heel. Good grippy soles.
Women's Dark Brown Boots. Size 5. $12. In excellent condition. Brand is Jessica from Sears. Model: Tamara. 3 1/2 inch heel.
Bass Black Leather Pumps (size 5 1/2 but fits like a 5) $15. Genuine leather. Very comfortable and great for work. Model / Style: Astrid. 3 1/2 inch heel, anti-slip sole. Excellent condition, worn only once (a little too narrow for me)
