Testing Aspects1. Safety
Is it slippery?Is the cleat still balanced?Do spikes become damaged with application?
2. FitDoes the spike cover fall off?Do the spikes fit within the holes?Do the covers fit the portion of the shoe?
3. Weight Capacity Max amount covers can hold
55
![Page 56: A-Traction Covers](https://reader036.vdocuments.site/reader036/viewer/2022062315/56815ded550346895dcc18b9/html5/thumbnails/56.jpg)
Testing Aspects Cont’
3. Time-Saving Easier to slip-on rather than
purchasing?4. Performance
Protect spikes from external surf?5. Physical Appeal
Product look effective? Attract customers?
56
![Page 57: A-Traction Covers](https://reader036.vdocuments.site/reader036/viewer/2022062315/56815ded550346895dcc18b9/html5/thumbnails/57.jpg)
Testing Procedure1.Safety
• Wear spike coversWalk on different surfacesIf the cleats slip on surf, it fails
2.Weight Capacity
• Wear spike coversAdd weights to the person to test the durability Record weight. Goal Capacity: 200 lbs.
![Page 58: A-Traction Covers](https://reader036.vdocuments.site/reader036/viewer/2022062315/56815ded550346895dcc18b9/html5/thumbnails/58.jpg)
Testing Procedure3. Fit
• Place spike covers on soleFail if covers fall off or become loose while walkingExamine if the spikes fit in given holes Examine if covers fit the sole of the cleats correctly (not too big and not too small)
4. Protection?
• Wear the spike cover and walkSpikes shouldn’t become damaged in any way
![Page 59: A-Traction Covers](https://reader036.vdocuments.site/reader036/viewer/2022062315/56815ded550346895dcc18b9/html5/thumbnails/59.jpg)
Testing Procedure5. Time-Saving• Time starts when he/she begins to put on the spike cover.
Time finishes when he/she takes of the spike cover. • Same person start a new time trial with spikes already on.
Start the time when he/she starts to remove the shoe. Stop the time when the other shoe is completely on.
• Compare the times. If the spike cover time was faster than the shoe-to-shoe time, the test is passed.
6. Physical Appeal• Test by giving the appearance of the product a score on a
scale of 1-10. (7 and above is a pass)

Problems in Design•There should be two layers to the shoe
Plastic: serves as the protection of the spikeRubber: serves as a safety precaution and
increases durability of the product
•Unachievable to design solution to fit all types of spikes
We chose the Nike Haurachi as our model shoe
