You can usually expect a price hike when a shoe manufacturer adds significant redesigns to a shoe--especially an adventure racing shoe--but that certainly isn't the case for the Adidas Jansten II M adventure running shoe. If you run in dry places, the Jansten II M has the highly breathable mesh upper to keep you comfortable over the long haul. That's one of the reasons that the Jansten II costs significantly less than all-weather trail and adventure running shoes It doesn't have the added weight and stifling expense of a waterproof and breathable membrane. Adidas significantly altered the design with a new Agion antimicrobial treatment and Otholite sockliner. While the Push Through Protection Plate (PTPP) in the midsole remains the same, everything else between the upper and the trail or pavement is enhanced, including a new compression-molded LightStrike III EVA padding and an all-terrain Traxion outsole. If you're looking for a trail running shoe that you can take to the races, especially on the sunny days, the Adidas Jansten II M is in step with your needs.
