I had my eye on another pair of Reebok ZigLite's but the price went up $45 so I started looking around for another pair of Reebok Zig's and found these. I LOVE them and I am so glad that I ordered these ones. These are designed for trail running, I use them for both outdoor and indoor working out and they are fantastic. The material is breathable, and the shoe itself is very light. It has increased traction on the treads making them great for dirt and gravel surfaces. The arch and heel support is probably my favorite feature of this shoe, I have high arches and workout indoors on cement floors so the extra support really makes a difference. I would recommend these shoes!
