Problem Statement
Spikes/ Cleats become worn out when walking on asphalt to a field/stadium/track.
5
Hypotheses
Design and manufacture a solution that will fit on the bottom of the cleats to protect the spikes from being worn out. This device will be used when the user is not using their cleats on the field or track.
8
Surveys
Do you use metal, rubber, or plastic spikes? Metal Rubber Plastic
What do you use spikes/ cleats for? Check all that apply Football Baseball Track & Field Soccer Golf Work Other
9
Surveys Cont’d
Do your spikes/cleats become damaged because of walking on asphalt/ sidewalks? Yes No
On a scale of 1-5, do you believe your performance decreases because of worn down spikes?
1 2 3 4 5 Would you use a device that protects the spikes/cleats from becoming
worn down? Yes No
10
Survey Results
13 people agreed that spikes wear down to the point where it should be considered a problem
8 people agreed that spikes were not worn down enough to be called a problem

Interviews
Interviewed 3 people All three interviewees agreed that their
spikes become damaged 2 of 3 interviewees also agree that having to
bring multiple shoes to an event is annoying These interviews prove problem statement to
be valid
15
Justified Problem Statement
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.
16
Solution should…
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
17
Possible Solutions
Each team member came up with 3 different solutions
The team decided on the best solution
18
Solution A: Spike Covers
•Blocks fit completely over the spikes
•Keeps spikes elevated above ground
•Reduces wear
20
Solution C: Rubber Sole
•A rubber sole slips on the bottom of cleat
•Keeps spikes off the ground
ProsEase in use
Easily put on/off
Comfortable to walk in
ConsSpecial size for cleat required
21
Solution D: Spike Plugs
•Rubber plugs put on spikes
•Keep spikes from touching ground
ProsEasy to put on
Small
Fits on any sized shoe
ConsEasy to lose
May take too much time to put on
22
Solution E: Retractable Cover
Rubber membrane on outside Stretchy rubber material extended over sole Covers heel, kicking portion Rubber sleeve covers entire bottom
23
Final Solution: F
Spike Plug with 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

The Spike Cover
A protective covering for the front and the back of the cleat
Keeps spikes from coming in contact with the ground
Has rubber bottoms for safety Easy to use Easy to store
28
Specifications
Weight Less than 8 oz.
Material Rubber
Usability Can be used with one hand
Storage Can fit into sports bags
Usability on Various Cleats
Can be used on various types of cleats
Size Various on foot size
Color Black
Use On Cleats
29
Function
Protect spikes from becoming dull
Protect spikes from coming in contact with the ground
Eliminate the need to bring multiple pairs of shoes to events
30
Form
The spike covers come in two parts The spike covers must be sized to fit onto
shoe Holes can hold spikes up to ¾” long
31
Ergonomics
The two parts of the spike cover are shaped to the heal and to the front of the cleat.
32
Ease of Maintenance
Primary tools needed Computer with Inventor Micrometer Prototype machine Belt Saw
34
Durability
Layer 2 was added to the product to insure durability.– It will protect the plastic from scratches– Keep the plastic from getting worn out
35
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)
36
Refining the 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
There was no way of making a solution that could fit all spikes
We chose the Nike Haurachi as our model shoe
37
Design Development
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
40
Assembly
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.

42
Assembly (Cont’d)
Suggested time of assembly: 1 day 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

Test Procedure
Fit Does the spike cover fall off? Do the spikes fit within the holes? Do the covers fit the portion of the shoe?
Safety Is it slippery? Is the cleat still balanced?
Weight Capacity Appearance
46
Test Procedure (Cont’d)
Does the spike cover protect the spikes? Do spikes become damaged when wearing
the spike cover? Does it eliminate the need to change shoes? Is it faster to use the spike cover than to
bring an extra pair of shoes?
48
Test Results
Failed the fit test Dimensions were not correct Spikes are different sizes Angles were incorrect
49
Fixing the Problem
Redo the measurements and drawings Realized that pressure is not the best way to
make the spike cover stay on. – Over time, it will become loose.
New Solution = Magnets
50
Magnets
Magnets will be implanted into the second layer of the product.
They will make the fit of the product more efficient.
