Vince Women's Oasis-w Sneaker

I saw this sneaker in Nordstrom and I thought it was cute. I come to Amazon and see the same sneaker in Malbec in my size about $100 cheaper than Nordstrom. So I purchased the sneaker but when it arrived the sneaker was so faded and the color was worn and washed out looking. This is not the same sneaker I saw in Nordstrom. I’m wondering if these are even authentic Vince sneakers? Or were they bad quality hence the reason for the steep discount? The sneaker is really comfortable so I may try to exchange it to see if I can get a better quality or I may just purchase it elsewhere.
