I spent a lot of time researching the best "nurse's" shoe. I really hesitated about buying these because of the price, but most shoes of this type are around the same price point. These shoes are simply AMAZING!!!! Wore them right out of the box. The heel does not slip, the sizing was perfect - even though I read that many people sized up, I did not since I was buying a wide width. The color is spectacular! I've worn them on long shifts, and no foot pain! Huzzah, Alegria! Great materials and find craftmanship. Now I can't wait to buy another color/pattern!!
