I am a bit surprised that Brooks came out with this latest new color scheme for the launch (the orange and yellow); considering they were already planning to kill the model. So it appears that Brooks is leaving no options for “middle of the road” lightweight and more minimal in design neutral trainers like the Launch, with their only options being the low heel toe drop Pure line or their more built up and heavier “traditional trainer” models. Their customer service rep confirmed this gap in their product offering and told me to stay tuned for future updates to the Pure line that MIGHT be a closer approximation to the venerable Launch model.”
Now, the Launch is not a shoe I run in these days, nor is the Green Silence, but both hold a place in my running history, and the Launch in particular was a fine shoe. It filled that niche between traditional trainer and lightweight racer, and it served me well during it’s time on my feet. I’d been surprised that neither the Launch nor the Green Silence received any kind of update in the past two years (aside from new color options) – this is fairly unusual in this day and age. Perhaps it was an early warning sign of their impending demise. I still know a lot of runners who use and think highly of both of these shoes, but in a market where running shoe “success” probably hinges more on mall and “big box” sporting goods store sales than sales to actual runners, profit was not sufficient for Brooks to maintain these shoes in its line. As a runner, this is perhaps what saddens me the most.Personally, I would have loved to have seen Brooks drop the Launch to an 8mm offset, thus shaving off a bit more weight, and position it as a lighter competitor to a shoe like the recently released, and newly 8mm drop, Saucony Ride 5.Anyway, if you’re a fan of either the Brooks Launch or Green Silence, looks like it may be time to stock up before they are gone. Or, perhaps we need to start a “save the Launch!” campaign. What do you think?There has been a great deal of discussion and debate over the past few years about how various aspects of running form can potentially contribute to increased injury risk in runners. One aspect of form that is often singled out as a major no-no is overstriding. That is, runners should not lengthen their stride by reaching out with the foot and landing with an initial contact point that is too far out in front of the body. If stride is to be lengthened, better to do it on the backside through increased hip extension.Indeed, a number of studies have shown that reducing stride length or increasing cadence (steps/minute) can reduce loading on the knees and hips (I summarize a number of these in Chapter 8 of my book), and thus form adaptation focused on alterations of stride length are thought to be of potential benefit in the treatment and/or prevention of some types of overuse injuries (e.g., tibial stress fracture, anterior knee pain).A recent study headed up by Elizabeth Chumanov from the University of Wisconsin sought to address how muscle activity in the lower extremity changes as step rate is increased (which corresponds to shorter strides). The study is titled “Changes in muscle activation patterns when running step rate is increased” and is published in the journal Gait & Posture. It’s a cool little study, and very relevant to the ongoing debate about form.
