This wave runs from the heel to the top of the spinal column. Your joints act as shock absorbers but are also severely put to the test. Choosing a good pair of running shoes is therefore essential for absorbing shocks and dispersing vibrations. * WHY IS THERE CUSHIONING IN RUNNING SHOES?: In order to keep on running healthily, you need to protect your body (joints, back, knees etc.) effectively from shocks and vibrations.The cushioning in the RUN CUSHION shoes has been designed to limit the impact of these repeated shock waves from your very first runs. * HOW TO CHOOSE THE RIGHT SIZE OF RUNNING SHOE: In order to ensure optimum comfort with your RUN CUSHION shoes, choose a size bigger than your usual size. There should be 1 cm between your toe and the end of your shoes as your feet will swell during exercise. * WHAT SIZES ARE AVAILABLE?: From 3 to 8 * HOW HEAVY IS THE JOGFLOW 100 SHOE?: 210 g in size 5.5
