During the 1920s and 1930s, advances in mining spurred development and immigration. The name was changed to Zambia upon independence in 1964. In the 1980s and 1990s, declining copper prices and a prolonged drought hurt the economy. Elections in 1991 brought an end to one- party rule, but the subsequent vote in 1996 saw blatant harassment of opposition parties. The election in 2001 was marked by administrative problems with three parties filing a legal petition challenging the election of ruling party candidate Levy MWANAWASA. The new president http://www.travelvisasexperts.com/userfiles/image/Flag/Zambia-Flag.gif launched an anticorruption investigation in 2002 to probe high-level corruption during the previous administration.

THE NEED According to soles4shoes and organization that has distributed over 13 million pairs of shoes worldwide, shoes are a necessity of life that help prevent parasitic infections that affect 1.4 billion people. Over 300 million children go barefoot worldwide and risk cuts, scrapes, and burns which lead to more infection that isn’t always treated. Diseases and infections such as hookworm are 60 times as common in poor areas without shoes such as African and Southeast Asian countries. In America, shoes are for style and comfort, yet the majority of world lacks even one pair of shoes. http://www.soles4souls.org/about/g reen.htmlhttp://www.yournextshoes.com/2010/08/get-yourself-some-toms-and-give-a-pair-of-shoes-to-a-child-in-need/
NEED FOR SHOES IN ZAMBIAhttp://www.news.cornell.edu/stories/Sept10/SigDonations.htmlhttp://www.worldvision.org/content.nsf/about/20101020-2010-TOMS-Shoes-World-Vision-Partnershiphttp://www.thezambian.com/zambia/w/zambia/climate-of-zambia.aspxhttp://atdaybreak.wordpress.com/In Zambia, over 600,000 children are left orphans because of AIDS. They are too poor to get allthe basic necessities and tend to lack proper footwear. They need it to protect themselves fromdiseases. If these children are provided with shoes they will have many new opportunities. Notonly is it very difficult formost children to walk thelong distance to schoolwithout shoes, but laws banchildren from attendingschools without a uniform,which includes shoes. Inorder to protect these childrenand give them hope, theyneed basic life needs, http://www.africaodyssey.com/zambia---when-to-goincluding shoes. Also, peoplein Zambia experience a rainy season from November to April each year in which around 500 to1400 mm of rain falls every year. This amount of rain is a hassle by itself. However, theadditions of unpaved roads, poor gravel and soil composition, and the lack of decent drainagesystems causes worse problems than just a lot of rain. A lot of mud is formed and standing waterbecomes a problem. Standing water provides homes for disease carrying insects and promotesthe risk of hidden sharp rocks that children can cut their feet on. Zambian kids need waterproofshoes that will protect them from all this.
Current Viable Solutionshttp://hubpages.com/hub/Make-a-Pair-of-Homemade-Hurache-Sandals -I liked this website because it gave a step-by-step tutorial on how to physically create your sandal. - The continuous string throughout the entire shoe would provide a simplistic way to create the shoe. - The way the string was cut with insert tab allows the user to create the shoe without having to do any gluing or sewing.http://homemadebyjill.blogspot.com/2007/12/homemade-cloth-baby-shoes.html I liked these shoes because of the elastic band. Although it is not the waterproof material that my group desires to have, we believe that it is possible to incorporate the band into our shoe.
http://www.vibramfivefingers.com/index.htm - I liked the Five Finger concept because it gave my group and I a visual image of ways we can shape the tire for the sole of the shoe. - We liked how both sides of the shoe and the back heel were fastened with one strip that connected in the front. o We would probably use a string instead of Velcro because it is more accessible to everyone.http://www.toms.com/?keyword=toms%20shoes&network=g&matchtype=e&mobile=&content=&search=1&gclid=CKmB-9GW9qYCFQNrKgodVhXFCw - The single cloth material for the whole shoe looked like a great idea because it was simple, easy to make, and had been done before so we knew it was plausible. - We would use a waterproof material as the cloth because we are designing a shoe for people in wet areas. - The slip on concept could pose as a problem because if the shoe get stuck in the mud it will slip right off (elastic band could fix this).http://www.hollowtop.com/sandals.htm
- The button strap is a great idea because we could add it onto the general shape of the TOMS shoes and that would keep them from falling off. o The buttons are easier to find then Velcro.http://www.barefootrunner.com/2009/03/review-wateraqua-shoes/ -These shoes are shaped like a sandal with the strap concept. - The sole is a tire - It requires no glue or sewing. (He cut the sole with tabs on the side and the tire as one continuous piece) - The shoes are extremely comfortable - They added the tab at the back of the sandal to add support and make it more durable in wet conditions (like mud and puddles). http://www.etsy.com/shop/netamir
- The water shoes are great because they are built to serve the same problem we are trying to solve. - They are designed to be in water and will dry quickly. - The gel-like bottom could be a good thing to use because it would provide maneuverability as well as durability.http://www.asia.ru/en/ProductInfo/741093.html - The overall shape of this shoe is very similar to the TOMS shoe, but the tightness of it would be great for keeping water out and their feet in.http://www.shoesreviewss.com/2010/12/09/water-shoes/
- If we designed the shoe to have holes on the side it would allow the water to seep out and this would keep the foot dry while still protecting it from dangerous elements (i.e. rocks, glass, etc.)http://www.muckbootsandshoes.com The boot shape is great because it enable the users to go into deeper waters without having to worry about it seeping into the shoes. It will ultimately keep their feet dryer and we hope to incorporate a boot like shape into our product.

SALT PELLET BAGS Salt pellet bags such as the ones shown hold around 40-80 pounds of salt which is used in water softeners, saline pools, and to deice roads. After using the salt, these bags are gotten rid of.http://rasmuscatalog.com/cgi-bin/mnlist.cgi?rasmus110/category/ALL ADVANTAGES DISADVANTAGES-Flexible -Appearance-Durable-Abundant/easy to obtain-Cost effective (people use them anyways)-Waterproof RAIN PONCHOS Rain ponchos are available at most convenient stores and are used as light weight, compactable coats when one gets caught in the rain.

CAR TIRES Car tires are durable and abundant. They are made from flexible steel and polyester cords and then encased by very strong vulcanized rubber. They should be changed about every 6 years, 10 at the most. They would be strong enough for people to walk on. They would provide a good outsole and support system for shoes.http://www.treehugger.com/files/2010/03/car-tires-made-from-corn-sugar-cane-switchgrass-bioisoprene.phphttp://www.ehow.com/facts_4865860_what-car-tires-made.html info INSOLESWhen one is walkingfeet go through twodifferent stages. Contact phaseThe foot is on theground. Swing phaseThe foot is in the air.The most damage isdone to the foot when itis in the contact phase.Certain areas of the footbecome strained overtime such as the bottomof the heel, the back of http://www.altwoodpharmacy.com/scholl-orthaheel-insoles-and-gel-the heel, the knee, and the balls pain-relivers/scholl-orthaheel-sensitive-feet-orthotics-small.htmlof the feet. These stresses canbe prevented by using an insole.
SOLUTION TO PAIN LAYERSLayered insoles help to reduce pain.Insoles such as Glidesofts use layers oflow friction materials to create theirinsole. This is because when the footpresses down the top layer moves forwardslightly as elastic bands stretch,and thenwhen the foot lifts up it goes back tonormal. This reduces feet pain because itreduces shear stress, or stress applied to asurface on a parallel plane. http://www.orthofit.in/web/bran ds/vasyli/diabetic-insole/
