Review on Ultimate Freedom and Comfort: Voovix Minimalist Running Barefoot Shoes for Women and Men by Ryan Saxton

They allow you to spread your toes. Most shoes squeeze them all together. I use them for walking (jogging) and they are better than any shoe I've tried for barefoot/forefoot technique. They lack some upper structure, so they're not suitable for activities that involve turning or changing direction quickly (golf, basketball, tennis) as the shoe doesn't wrap your feet as they turn. But for walking, running, rowing, swimming, etc. they are great. And affordable. The upper is stronger than the previous generation I tried.
