Start with 2-4 low-intensity barefoot strides, focusing on landing softly on your midfoot.
start slowly. Begin with a short run. 1 mile, no more than 2.
The 10-minute rule. Run every other day, increasing distance no more than 10 minutes each time. Rotate with your current shoes to maintain your fitness/training for at least 2 weeks.
Build your foundation. Do not introduce speed, intensity and distance until you have adjusted to the Newton Running shoes.
Why bother? Your connective tissue (muscle and tendon) and structure (the fine bones in your feet) need time to strengthen and adapt. Newtons allow your foot to feel the ground as if you were running barefoot. If you increase your running volume too quickly, you may experience calf tenderness.
Focus on form. Good Natural Running form allows you to run with greater efficiency and less injury.
Newton Shoes Require an adjustment period due to the lower heel to toe ratio. This is what Newton recommends to adjust to your new shoes.
