The serious contenders in this category, both Running Brands and Outdoor Brands continue to show their willingness to support shoes for casual, moderate, and extreme trail running, offering more and more shoes for consumers to choose from. Technology is at an all-time high, and more waterproof offerings are available than ever before. The Hairpin is a serious trail runner which features a carbon rubber tread for security and durability. The minimal stitching across the midfoot keeps things light but secure. Loop lacing stabilizes the foot without stangling it, maintaining the balance over the midsole. The midsole is a healthy layer of EVA foam, balanced and flexible enough to handle rocky terrain as well as some pavement. With any luck this new trail series will see Fila into a future of performance trail running.
