These are trail shoes, but I haven't used them on trails. I've used them in the gym for working out because I wanted some lightweight shoes that allowed me to feel the ground for balance.

What I noticed was that even though there are grippy bumps all over the sole, they are slippery on indoor floors if they're wet. So definitely be careful about that, if you're going to be using them for gym work, if there is sweat, or any type of moisture on a hard floor like a basketball court, you are going to slip.

Other than that, my only other complaint is that the tongue has a hard time staying in the center. It doesn't have one of those little "keeper" loops that you can lace through, so sometimes it slides to the side and bunches up.
