The North Face Women's Ultra 104 GTX XCR Trail Running Shoe. The durable synthetic upper and TPU toe cap protect your foot from rocks and roots while a beefy UltrATAC outsole provides excellent traction in the sketchy terrain. The North Face used a waterproof breathable Gore-Tex XCR insert to keep the Ultra 104 shoe bone dry on the inside even when it's completely muddy on the outside.
