HYPOTHESIS SMALL SIZE OF SIZE CHART AND UNCLEAR SIZE LABELS LEADS USERS TO SELECT THE WRONG SIZE FOR THEMSELVES
STORELLI H O M E PAG E
Pictured above is the main page for the product. The layout is clean and visually engaging, however the size chart is too small to be seen by the user which inconveniences their digital experience.
Focusing on the size chart, Storelli does not give the user a clear guide as to how to obtain your size. Additionally, the abbreviated size titles might confuse some users.

Padding is too bulky around ankle area if wearing certain type of cleat
“Too much padding around the ankle area”
I needed to find thinner material that would still absorb a big impact. I created a pressure sensor with conductive fabric and test various materials
Adhesive Sheet Velostat Conductive Fabric
How it works. When weight is applied to the pressure sensor the multimeter converts this action into ohms (an electrical unit). The more weight that is applied, thesmaller the ohm unit becomes and vice versa. To measure if a material will be good at absorbing impact it is placed on top of the pressure sensor and a weight is applied on top of it. If the ohms measure is bigger than another material measured at the same weight it is better at absorbing impact.

SUMMARY LEG GUARD PROTOTYPE PROVIDES PROTECTION WITHOUT INTERFERING WITH THE USER’S PERFORMANCE. ADDITIONALLY, IT ALLOWS FOR EASILY CUSTOMIZABLE PADDING.
NEXT STEPS FOR FUTURE ITERATIONS OF MY MODEL, I WOULD CONTINUE TO WORK ON THE DESIGN AND PLACEMENT OF THE PADDING. THE PADDING UNDER THE CALF WOULD EXTEND FURTHER DOWN TO COVER THE ACHILLES TENDON. SECONDLY, I WOULD CREATE VARIOUS DESIGNS FOR THE ANKLE PADDING TO FIT MORE COMFORTABLY WHEN WEARING SOCCER CLEATS.
