What Are Negative Heel Shoes?
You may have noticed the latest in footwear technology hitting the streets, the negative heal shoe. Forbes Magazine recently included them in an article on 20 Ways You are Getting Ripped Off. You have seem them, they are big and bulky, resembling orthopedic or moon shoes. I have been getting a lot of questions from clients about these shoes and if they are worthwhile. Common brands include Sketchers - Shape Ups, Reebok's - Reetone, Fit Flops, and MBT, among others. These shoes are ergonomically designed with a soft, depressed heal, and rocker bottom, to promote greater lower limb muscle recruitment. They claim to tone leg muscles and abdominals, improve posture, and burn more calories. The marketing campaign, targeting mostly women, are a goldmine. Who wouldn't want to reap these great health benefits.
Are These Health Benefits Real or Hype?
Unfortunately, a lot of these claims are unfounded or based on company financed research and anecdotal evidence. They are the latest foray of quick fix fitness gimmicks. While they may serve some purpose in the realm of balance training and simulating a hyper-proprioceptive environment, there is little research to support efficacy of instability training anyway. With the exception of your lips and genitalia, your hands and feet contain more nerves than any place in your body.
Wearing these shoes, pads and dulls vital sensory input from the ground and up through your sensory rich feet, via proprioceptors to your brain. Intentionally placing yourself in such a precarious position may expose you to injury, ankle sprains, falls, etc. I would not allow a client to do anything beyond moderately walking in them. They are definitely not conducive to resistance training, which will yield greater health and weight management results than a change in footwear; $100+ footwear!
Yes, you may initially feel an increase in muscle activity. Any change in your footwear and or posture will elicit a similar effect until your body adapts and realigns itself. Better to reinforce a natural, healthy gait pattern, strengthen the muscle in your feet, and improve your posture with proper alignment, then to reinforce a negative pattern, shifting your weight onto your forefoot, stressing your knees, and anteriorly rolling your pelvis, crunching your sacrum.

So what can you do to improve leg and abdominal toning, improve your posture, and burn more calories? Stand up from your desk and take your shoes off. Turn your feet parallel to each other, toes spread, big toes straight ahead, slightly tuck your tailbone and engage your abdominals, take a deep breath, pull your shoulders back, tuck your chin, and lift the crown of your head towards the ceiling.
Now stand and be mindful of your renewed sense of posture and alignment. Maintain this mindset and walk around the room. Feel your feet in contact with the floor and the transfer of energy up through your feet, into your legs, through your core, and up to your neck, shoulders, and head. Continue to be mindful of this posture with each and every step you take and notice the immediate benefits in muscle activity.
Remind yourself of this postural ideal tomorrow as you go about your day and start reaping the benefits. Because you can't walk around barefoot all the time, consider a flatter soled shoe that keeps your foot closer to the ground.
