I've tried 4 different barefoot trail running shoes, 2 Merrells, minimalist WHITINs and this signature 'Tesla' pair. These are the guards. My photos compare this pair to the Merrell Vapor Glove 3 cotton gloves, which are 3 times more expensive. They have a much more comfortable upper and the feel and weight are almost identical. My only complaint (so far) is that they just have all these sporty color schemes and no neutral colors that would go better with business casual attire. NOTE TO TESLA: Please make the exact same sneakers in neutral colors, I will definitely be buying more of these!
