Step 1- Problem Statement
Spikes/Cleats become worn out when walking on asphalt to a
field/stadium/track.
Step 2- Brainstorming
Consider Source of Problem Deals with cleat shoes wearing away when
walking
Friction/ contact of shoe with track field surface
Athletes’ amount of shoe usage
4
5
Background
Experience– Joe plays football– Joey played baseball
Knowledge from peer athletes – Conversations– Environment– Issues with track surface
6
Hypotheses
Impossible/difficult to improve upon outside factors
So, Improve features of cleat shoe– Design & manufacture solution to fit on bottom of athletic cleats – Solution will provide protection so cleat shoe will last longer– This device will be effective when user is not using cleats for
their main purpose
7
Step 3- Research/ Justifying the Problem

Inventor: Perron, Jr.; J. Edward [Metairie, LA]
Patent Filed: March 31, 2005Patent Number: 7,487,604
Testimonial from Patent 1
Shoe cover insert innovation– enhances performance of soccer shoe
Conventional soccer shoes have problem with vertical component– design needs to be modified
Design includes an insert that:– cushion the foot– provide foot stability – motion control; reduce fatigue– extend the float time of a runner and – increase the jump height of the wearer– extends vertically.

Justified Problem Statement
Conclusions based off research– Expert feedback– Patents– Online resources
Athletes need to wear a different pair of shoes while walking on anything other than their playing field, otherwise their spikes will become damaged or dulled. EXISTS
18
Step 4- Design Criteria
Protect spikes from becoming dull
Protect surfaces from damages
Eliminate the need to bring multiple pairs of shoes to events
Take less time than switching between shoes
Design Criteria Cont’
Manufacturing Cost Material Ease of Use Storage Durability

Step 5: Possible Solutions
Each team member came up with 2 different solutions
Evaluated pros/cons, scored off of criteria screen
21
Solution A: Spike Covers
• Blocks fit completely over the spikes
• Keeps spikes elevated above ground
• Reduces wear
23
Solution C: Rubber Sole
• A rubber sole slips on the bottom of cleat
• Keeps spikes off the groundPros
Ease in useEasily put on/offComfortable to walk in
ConsSpecial size for cleat required
24
Solution D: Spike Plugs
• Rubber plugs put on spikes
• Keep spikes from touching ground
ProsEasy to put onSmallFits on any sized shoe
ConsEasy to loseMay take too much time to put on
25
Solution E: Retractable Cover
Rubber membrane on outside
Stretchy rubber material extended over sole
Covers heel, kicking portion
Rubber sleeve covers entire bottom
26
Innovation Solution F: Spike Plug W/ Retractable Cover
– Spike plugs easily attach to bottom of athletic spike shoe
– Retractable stretchy sleeve holds together spike plugs
– Allows attachment of all five plugs without effort– Retractable cover provides tight support all around
shoe– Prevents shoe laces from becoming untied

Supplies and Cost
The cost to make the product is fairly cheap Most of the project’s cost comes from the
prototype machine The cost to produce one spike cover (both
parts) is about $25 (according to Stephen Buchs)
Material Cost

Assembly Parts
Part Name Part Description
A1 Front, Top layer. Made from plastic.
A2 Front, Bottom layer. Made from Rubber
B1 Sole, Top layer. Made from plastic.
B2 Sole, Bottom layer. Made from rubber.
45
Step 8: Assembly Process
2 Parts to the solution– The front of the shoe– The sole of the shoe
Each part is divided into 2 layers– Top Layer: made of plastic– Bottom Layer: made of rubber
46
Assembly Process
Suggested time of assembly: 2-3 days Assembly procedure
1. Gather Materials
2. Use prototype machine to make layer 1 of both parts
3. Cut out layer 2 with belt saw
4. Use shoe glue to attach parts Part A1 to A2 Part B1 to B2
Step 9- Test & Evaluate
Evaluate performance of cleat covers Individual from team make use of covers Estimated time: 2 days to perform test 3x Equipment needed:
– Team members– Data tables– Stopwatch– Weights– Prototype– Cleat shoes
47
48
Testing Aspects
1. Safety Is it slippery? Is the cleat still balanced? Do spikes become damaged with application?
2. Fit Does 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
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?
49
Testing Procedure
1. 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.
Testing Procedure
3. 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
Testing Procedure
5. 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 spike– Rubber: 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
56
Step 10: Refinement
Redo the measurements and drawings– Used micrometer– Calculations
Learned pressure does not help covers from staying attached– Over time, it will become loose
New Solution = Magnets
57
Step 11: New Solution- Magnets
Magnets will be implanted into the 2nd layer of the product
They will make the fit of the product more efficient
Solves problem statement Cover protect spikes? Spikes still damaged with cover on? Eliminates need to change shoes?

Did the same person perform the testing procedure? Do the results reflect a problem with the testing
procedure? Do the results reflect a problem with the testing
criteria? Do the results reflect a problem with the materials
used for the prototype? Do the results reflect a problem with the quality of
the building process of the prototype? Do the results reflect a problem with the design of
the prototype?60
