Waiting on resolution to hopefully up the stars...but they have an awful smell. I thought it would go away but eventually made me nauseous. I couldn't think past it. A rubber meets diesel smell. Hope I didn't just poison myself during the 3 hours of wear. I love online shoe shopping and this experience may have just turned me off from ever buying another pair online. I couldn't even sit through a meeting without thinking the smell was diruptive. I washed my feet and changed shoes. Emailed the seller to see if this is a known issue and how to resolve. Otherwise- cute and fits and is comfy.
