I just received my Vivobarefoot light brown Gobi's in the mail today! And i have to say, they are GREAT! They have a great style, with just a suede material, waxed laces, and the patented ultra thin sole. I immediately put them on and tested the feel of them with and without the insole. They feel really good without the insole but to each his own. I walked around on rocks and ran around a bit and didn't feel a thing. I noticed with the Ra that the description said to wear socks (on a different website), but the Gobi didn't, so I tried them without socks and it also feels really good and comfortable (the suede helps with that). Also i usually wear a size 12 but I ordered a 13 and it's the perfect fit with a little bit of big-toe room. Overall, I ABSOLUTELY recommend this shoe to anyone, and I am going to be a lifelong customer!
