"I can't say it's the most comfortable shoe I've worn, but what is unless its a slipper?! For a high heel I didn't feel unstable, the shoe feels sturdy and I don't feel like my whole stride is pushed forward with my knees way bent. The toe box is a bit narrow but I have bunions so this is tone expected. Not for walking around a lot but good for the office. I LOVE that it fits snugly around the sides of the foot and doesn't slip off the heel."
