The most uncomfortable shoes and a serious waste of money

I bought pumps at Woolworths on -line for R350 a couple of months ago to use the for work since I am on my feet majority of the time. The fact is that I could never keep them on my feet for anything more than 10 minutes. They have been the most painful, hurtful shoes. I have kept them in my wardrobe, till God knows when. It has been a complete waste of money purchasing these shoes as they do not serve the purpose that I intended for them
