Introduction: Put a Spring in Your Step
Hotrod your United Nude heels: Use this method to transform your United Nude Eamz shoes into a Pedestrian Vehicle! Great for ladies everywhere who are trying to be greener while maintaining their fast paced lives.
Step 1: Obtain Your Eamz Heel
United Nude Shoes makes the Eamz heel, which is good for adapting with a coil spring.
Step 2: Calculate
your personal spring constant, or k value by Hooke's Law:
F = -kx
Derive your F, or force, value from your weight.
For example, for a woman who is 125lbs, F = approx. 570 (125lbs / 56.7 kg x 10.8 m/s2)
x is the distance that the spring compresses, which will be approximately 3/4" (or less)
Plug it into the formula, and you have your k value. Use this value to search for your personal coil spring.
Step 3: I Used a Coil Spring From Ajaxwire
Find a spring that is approximately 5/8" in diameter so it will fit. Screw one end of the spring into the Eamz heel.
Step 4: Obtain a Plain Rubber Stopper
the kind used to cap test tubes. You can get these from any chemistry supply or rubber supply store. To fit into the 5/8" spring, the 00 stopper size works best.
Step 5: Whittle the Rubber Stopper
With the wide end of the stopper on the table, use an xacto knife to cut away the rubber. You want to have a narrow rubber cylinder attached to a fat cylinder at the bottom. Make sure that your stopper is not more narrow than the space inside the coil of your spring.
Step 6: Insert the Shaped Stopper
into the spring. Because of the elasticity of the rubber, you can simply screw it in. Make sure the end of your spring is touching the wide end of your stopper.
Step 7: Repeat the Process
with your other Eamz shoe, and you have a completed pair!
