Introduction

In the mid-19th century, shoes began to be mass-produced in factories and thus became more widely available to the general public. Men wore laced or elastic-sided ankle boots. Women wore heeled shoes, low cut or laced or buttoned to the ankle. Canvas-topped, rubber-soled shoes (sneakers) were introduced for sports.

The 20th-century emphasis on youth and informality has influenced shoe design. Male footwear includes low, laced oxfords in various leathers, slip-on loafers, ankle boots, and specialized sport shoes. According to changing fashion, women have adopted high, spike, or low heels, with thin, platform, or wedge soles, in closed shoes or sandals; in the late 20th century, tight, knee-height boots were popular for day wear. With the growing interest in exercise for physical fitness, various adaptations of running shoes have become the universal footwear for men, women, and children alike.

Georges de Mestral, a Swiss engineer, invented Velcro in 1948, after investigating the clinging behaviour of burrs, which stuck to him and his dog during their hunting expeditions. Examining a burr under a microscope, he observed that the surface was covered with hundreds of tiny hooks that would catch and hold on to cloth, hair, and any other soft substances that offered thread-like projections.

Prevention of injuries is becoming a vital part of sports training and activity. Apart from the general precautions that apply to all forms of exercise, which includes warm-up and good technique, sports participants need to follow guidelines specific to the sport being played: the appropriate clothing and shoes; equipment in good condition and matched to their capacities; a safe environment; and training in the skills needed for safety. These might include balance, flexibility, good technique in movement and gait, and strength in the muscles and ligaments most often used.

Evaluation

When I was performing this experiment, I had performed safely and had listened to all the teachers instructions, but I had made a few mistakes like some times the water had over flowed because I had put the piece of trainer in too fast, so I had to perform the task all over again. Other than this I think I performed this experiment very well.  

Weathering

Introduction

Weathering is the breakdown of rocks and other things by chemical processes at the surface of rocks or other items, this is usually done by the rain weathering on an item makes it go smaller or wearing it away. Weathering also makes rocks go smaller which leaves behind debris which is then carried away by erosion by the wind, ice, water or the sea, testing the trainer is very important because it then tells us how long it would last outside when exposed to water.

Method

  1. Firstly I had to cut up the trainer and took the pieces that I needed for this experiment.
  2. Then I measured each of their lengths and put then into a table.
  3. Then I measured each of their widths and wrote them down into the table.
  4. After this I calculated the area by doing width x length
  5. Then we soaked each of the pieces in water and made sure nothing was dry.
  6. Then we dried them out with a hair drier.
  7. After this we had measured the length and width and put this in our table.
  8. Then we calculated the area by doing width x length.

The diagram below shows how we soaked the piece of trainer:

Conclusion

Method

  1. Firstly I got a piece of trainer that I had already cut off the trainer.
  2. Then I used sellotape and taped the piece of trainer to the front of the cart.
  3. Then I drew a line on the top of the cart and put the block behind it.
  4. Then I put the cart at a reasonable distance as possible.
  5. Then I let go of the cart and watched it run drive down the ramp and into the wall.
  6. Then I used a ruler to see how far the block went when the cart collided with the wall.

Diagram of test

The diagram below shows the method I used to find the collision distance of the trainer pieces:

Conclusion

I think that the sole and the insole have the same comfortableness because they both made the block move at the same distance as each other, but the thicknesses are very different from each other.

Evaluation

I think that I performed this task really well, I had to find I own distance from the wall and didn’t get any help from anyone, but I still performed the task perfectly.

Conclusion of all experiments

In this coursework I had found the testing for wear experiment the most simplest from all the experiments and found the testing for stiffness experiment the hardest because I had trouble clamping it down and finding more weights to hook onto the shoes.

Evaluation of all experiments

If I could change my trainer I would make it less stiff, so that the foot could move around easier, but other than that the rest of the trainer was good and had good grip which is very useful for a person that does a lot of running but could still slip on some surfaces.
