Toe spring is in the front of
Toe spring is in the front of a shoe. If you put your dharma on the floor. The front of the sole has a upward curve. This is toe spring. Each company designs it at different degree of upward curve. Toe spring purpose is to aide in push off phase of walking. Typically this is designed in cause most shoe soles are hard, and inflexible which prevents natural barefoot movement. This toe spring puts toes into unnatural hyperextended position. If you look at your barefoot on the ground the toes are flat on the ground. When you put your foot in a shoe the toe spring causes your toes to no longer be flat, hence hyperextension. Prolonged hyperextension causes unnatural tension on the plantar fascia that will then weaken the arch. Toe spring changes are natural gait, and is unhealthy for our feet.
It's time to do away with toe spring ! As of now toe spring is common practice in shoe design so min shoe companies are continuing to include this in design. I don't think everyone is aware of the bad effects of toe spring. Like anything it takes time to make change. Also min shoe companies seem to want to make changes in phases. They don't want to make too many changes to quickly in fear of consumers not buying the product. It really is time for those of us that are aware of the negative effects to tell these companies to rid toe spring from shoe design.
Hot foot is a known issue that is created from wearing enclosed shoe systems. Hot foot does not really exist in open footwear, or barefeet alone. A enclosed shoe is basically a oven. due to tight uppers, laces, material that does not breathe sufficently, instep support panels, tongue, etc. Simply no air flow. Or laces tied too tight restrict blood flow. This design raises the temperature of your feet. Adding socks makes hot feet syndrome even worse. The very warm temperatures cause sweat. The combination of sweat, and heat is not a healthy environment. Due to these increased temperatures shoe fabrics can leach into foot. Which can leach nasty chemicals in some cases over time. This can cause allergic reactions depending on the shoe, fungus growth, blisters, etc. Foot becomes a lab growing all sorts of things if you wear them enough. Millions of shoe addicted americans go to the doctor each year because of hot feet syndrome. This is what causes the infamous smelly shoes.
I don't think I can explain it much better then this. Lastly the degree of hot feet varies by individual. Some have it more then others. Maybe for Adam not so much, but for many it is not a fantasy. It is very real.......
