Brooks will be ending the long run of the Launch and Green Silence series in 2013. According to Brooks, the Launch program is not generating enough sales volume to warrant continued updates. So users of the Launch will probably look towards the Pure Flow as a replacement. It is also sad to hear that Green Silence will be put to rest in 2013. The GS was one of the first running flats to make an Eco-Friendly statement. As a leader in the Green Shoe movement, the GS was 75% post-recycled, as-well-as a biodegradable insole and collar foams.
