You are invited to a challenge of BALL OF FOOT CUSHIONS VS BALL OF FOOT CUSHION. I will send you a pair of ball of foot cushions FREE so you can do the challenge with me. I will send you a unique newly invented pair of PORON foam ball of foot cushions FREE with shipping included ($15.85 value) if you agree to do the challenge of putting the Killer Heels Comfort ball of foot cushion in either of your shoes - left or right - and any other brand name ball of foot cushion into your other - left or right - shoe. The challenge runs until June 30 2019, however I would like you to report at the 30 hours mark of time wearing your shoes whenever that occurs. My challenge is to walk for 30 hours with a Killer Heels Comfort ball of foot cushion in my left shoe and an Aldo Foam Instep Cushion in my right shoe.
You may choose ball of foot cushions made of any material such as memory foam / any other type of foam / gel /resin / fabric / composite etc. for your other shoe. As the shoes to put the cushions into - you may choose any flats, runners, slides, sandals or flipflops (or closed heel pumps) that you already have or purchase new that have a flat insole inside. Please run the test for 30 hours of walking, standing or running in the shoes. (That's all day wear of about 3 hours x 10 days of standing walking in a typical work day in flats (or closed heel pumps ) or maybe an hour a day of running/walking in sports shoes or tennis shoes for a month, etc. Any combination of activities is fine as long as you are standing/walking in the shoes. )

Killer Heels Comfort ball of foot cushions are different from any other forefoot inserts or cushions available for sale anywhere. A worldwide search of existing art of previous patents and all shoe inserts sold globally has not shown any other shoe inserts or cushions that have the materials and features that make these ball of foot cushions unique. Their uniqueness is the reason they have utility patents from Canada 2015, Europe 2017 and USA 2019.
THE BALL OF FOOT CUSHION INSERTS ARE UNIQUE IN FOUR WAYS TO ADD COMFORT TO YOUR FOOT
ONE: The material they are made from is open cell polyurethane called PORON. They are the only ergonomic shoe inserts sculpted from PORON, a polyurethane foam that rebounds after every step and never flattens. PORON cannot be injection molded like most other foams and gels. The PORON inserts are made by sculpting a shape starting from a flat 6 mm (1/4 ") sheet of PORON using a proprietary process innovated by a manufacturer in Canada.
PORON is commonly used as a layer of insole in good quality athletic shoes, or built into high priced fashion shoes as cushioning that never flattens. * Most shoes have cheaper low quality foam cushioning that flattens over time.
TWO: The inserts are custom fitted. The placement of the cushion part is precisely under the centre of the ball of the foot at the point of greatest pressure. The toe grip is placed at the exact same angle as the transverse base of the middle three toes. Custom fitting ensures that the 'bump' of the toe grip fits into the 'hollow' under the three middle toes. The custom placement of the insert by each user ensures that the cushioning provides maximum function using minimum space for their unique foot.
THREE: The middle section of the rounded cushion is 4.5mm at its' centre - the point of greatest pressure - tapering to 2 mm at the edges so it will not crowd the inside of the shoe. The greatest pressure point underfoot is under the middle metatarsal head. (this is the big bump under the ball of the foot at the base of the middle toe. This is often the area of a callus because it sticks out the most and is the contact point for pressure. The PORON foam rebounds or springs back - ensuring the ball of the foot has a 'fresh' cushion under it at each step. After many years of daily use the surface of the foam may show signs of wear from accidental snags but the foam will not have flattened.
FOUR: The toe grip is a raised cross bar that is 6mm at its centre. The cross bar tapers at each end and fits only under the middle three toes ensuring that the big toe has room to function properly to provide propulsion to the foot, and the little toe functions to provide balance to the foot. The bar cannot be seen from the front or the sides of the foot. The bar stops all forward movement of the foot inside the shoe, and the blunt ends of the bar stop the foot from moving sideways. These functions are especially value when the foot inside the shoe must be stabilized such as in active sports where the foot has sudden stops and starts, or in high heels when the foot needs to be stabilized for a more natural and less tiring walk or in slides or thong sandals when the toe grip bar helps keep the foot comfortable & the shoe on the foot!
Caution: If the shoes you choose are ballet flats with very thin bottoms stop the challenge if you seem to be getting sore bottoms on your feet as that could be plantar fasciitis, a foot condition that is sometime brought about by walking extensively on hard surfaces in thin bottomed shoes. Switch to shoes that have thicker soles and heels if you want to carry on with the challenge and request a second set of ball of foot cushions from me. I want you to be safe.
Open Cell vs Closed Cell Materials (from PORON website blog by Nicole Perry) EVA, latex, and low-density polyurethane are common, commodity types of materials. Low-cost and available from many manufacturers, they can run a broad spectrum for properties and performance. The most prominent difference in performance between these materials and that of open cell PORON Comfort is that EVA is a closed-cell material, while latex is a water-based polymer. While both EVA and latex can be incorporated into the shoe’s construction, performance and comfort decrease over time with weight and moisture exposure. This type of substandard performance is not evident during initial wear of the shoe, but fit and comfort begin to change the longer the shoe is worn. When the consumer goes to purchase their next pair of shoes, they’ll associate an unpleasant experience with that particular brand of shoe.
Blogs written for high heel wearers should give useful and good - and safe - information about high heel comfort. I write blogs where I try to do that - plus dispel myths and bad "tips". I have an offer for two FREE high heel shoe inserts sets if you buy one from Amazon. This is your chance to try these innovative design ergonomic high heel shoe inserts in THREE of your favourite heels for the price of outfitting ONE.
Platforms, stilettos, high heeled sandals, kitten heels, pumps or mules; 1. Wear the right size shoe 2. A steeper ramp creates more discomfort; 3. Check the heel placement. 4. Add foam cushioning.
