OluKai Ki'ihele Women's Comfortable Slip-On Sandals - Lightweight & Supportive Beach Shoes for Walking, Travel & Summer Outfits

I really like the concept of this shoe - it's a sneaker that easily converts to a mule. Both worlds in one shoe - mind blown.Execution needs improvement, though. When you fold the heal down to wear it as a mule, the sides are bulky, because of the material it doesn't fold flat on the sides. It's a little uncomfortable that way (you get used to it), and detracts from the look of the shoe. It's not a deal breaker, hopefully the design will improve over time.I found these true to size lengthwise, but felt they were too snug on the top of the foot and toe area. Maybe the issue would resolve itself as they are worn, but I didn't want a bump where my big toe is. I ended up reluctantly returning them.All in all, I think it's a quality product, at least worth a try.
