One of the newest running shoes hitting the market is the Adidas Springblade, which adds a rather unconventional design element to the old familiar running shoe.

Sixteen polymer blades spring from the bottom of the Springblade’s sole, designed to act like little springs and add a boost to a runner’s gate. The shoe,Find a great selection of christian louboutin boots deals ! Click on any of the links below. which goes on sale Thursday, costs $180. While you might wonder just how well such a cutting-edge, expensive shoe might sell, remember that some of the hottest “barefoot” or minimalist running shoes provoked some quizzical looks when they were first introduced too.

Adidas says the blades of the Springblade are designed to take the energy from a runner’s foot landing on the ground and redirect it.

“Typically, if you get any energy coming back from the landing impact in a shoe, it goes back up,” James Carnes, the head of global design for Adidas, told Fast Company. “This is designed so that when you push down the blades help propel you forward.”

The design brings to mind the curvy prosthetics that the South African Olympian (and, it must be noted, accused murderer) Oscar Pistorius wears when running. Pistorius’ prosthetics, made of special carbon fiber, store energy when he lands on them, then release that energy when he lifts his leg up.

While that might seem like a clear advantage over able-bodied athletes, Pistorius ends up having to work harder with the rest of his body to compensate for the fact that he has no calves or feet. All of the muscles in the leg play into locomotion, so the cheetah-like “Blade Runner” prosthetics are mostly just bringing an amputee up to par with those still in possession of their biological limbs. Pistorius also ends up slower at the beginning of the race than other runners, since the cheetah blades don’t provide nearly the blast-off force that a runner’s calves and feet give off the starting block.

Whether or not this energy-storing principle will turn out to be an improvement on the running shoe design remains to be seen. Adidas has finely tuned the Springblade’s features to adjust for different sizes -- the blades on a size 10 men’s shoe will be differently calibrated than the blades on a woman’s size 7, according to Gizmodo.

The positioning of the Springblade’s blades also mean this is likely a shoe best-suited for tracks and city streets. One can imagine sand, mud or gravel getting caught in between the blades quite quickly on a trail run.

The idea of putting extra spring in a runner’s step isn’t totally new -- in fact, earlier in July, a researcher at the University of Central Lancashire unveiled his design for a sneaker that incorporates lightweight springs from a UK mattress company.Latest Trends in Wholesale gucci handbags, Wallets and more‎.

Fighting fires is just one part of their job at the Germantown Fire Department.welcome to replica jewelry web,Free shipping‎! The majority of the firefighters are also certified as emergency medical technicians. They respond to all emergency calls in the village. On top of it, many of the firefighters in Germantown have full-time jobs outside of the Fire Department and do it because they care. (The majority of the staff is either paid on-call or part-time.) Many said it's in their blood. No one else could save a life in Germantown if they didn't sign up to do it. For that reason, the fire department could use more personnel.

Before tackling the training exercise, I saw their life-saving techniques in action. The emergency calls ebb and flow. Some days there are a dozen, others one. There were five the morning I came to work there. Of course, I didn't get there until noon when calls coincidentally subsided. Still, we kept busy until a call came over at 6:30 p.m. for an elderly woman suffering from a seizure.

It was go time. We jumped into the ambulance and were off. I was in the second ambulance to arrive. I watched three EMTs provide initial medical care and transport the woman to the hospital. All of which was done with great care,Find a great selection of Michael Kors Satchel Bags 2013 New Arrival at hotmkbags! teamwork and precision.

The men wore many hats that day. By the time I went home I was exhausted, but they continued to work and respond to calls throughout the night.

I didn't know what to expect going in the shoes of a Germantown firefighter. The rush to save a life made my rush to meet deadline seem trivial. The adrenaline of crawling through that building gave me a sense of accomplishment I haven't felt in a long time. Still, not everyone is cut out for the job, myself included, and it takes a unique individual to do what firefighters do every day.
