// Protecting the vitality and mobility of those Aging in Place

Spring 2020*

Sōl aims to empower those aging in place by providing a footwear solution as stable as it is easy, as comfortable as it is capable, and as appropriate as it is stylish.

Sōl is making slippers that don’t slip-

because aging in place shouldn’t mean staying in place.

Pitchdeck Presentation + Final Concept Overview


 

This project is the outcome of a research oriented design class aimed at designing for death. It was our responsibility to familiarize ourselves with the subject, trends surrounding it, and trends beyond it. We were asked to get personal. I gravitated towards the activity decline some people experience in old age, seeing accessibility to footwear a hinderance.

The final design pictured above features a multitude of innovative concepts designed to improve the safety and performance of slippers. Starting with the front toe cap, multiple materials are used with specific properties designed to mitigate specific problems in navigating homes and elsewhere. An extended rubber toe guard provides grip and toe protection. An inner semi-rigid and frictionless plastic piece adds more protection and allows the foot to slide in potential tripping scenarios when walking up stairs, hence the lack of friction. Hidden beneath the translucent rubber and plastic is an LED light activated by tapping your toes in order to provide better visibility during night activity. Moving on to the sole, supportive wings of EVA foam imbedded with semi-rigid plastic cup the heel and begin to support the back of the heel. However, they remain flexible and with a large gap in the back to allow the foot to slide into the shoe as it would with any other slipper. To ensure the foot stays secured, a flex groove has been positioned just behind the ball of the foot so that the slipper does not create blisters or remove itself from the heel. Looking above the sole, the upper is designed in two pieces to ensure there is no friction and that anti-microbial fabric is in contact with all areas of the foot. The two pieces also have Velcro between them, allowing for proper adjustment of the fit. The outermost fabric has a flex groove towards the front of the foot to accommodate for foot swelling, wider feet, or orthopedic inserts. Which brings me to my last feature, inserts! This is the first and only true sleeper that features insole inserts, the likes of which can be customized and specified at the time of purchase. If you have doctor-prescribed orthopedic inserts, or prefer a different pair, you can also remove the existing insoles and put your own in. This is also great for maintaining clean shoes and extending the life of your slippers.

 

Final focus exploration


Easy-access hiker with an ultra stable and grippy outsole, breathable micro-mesh panels surrounded by composite “bumpers”, and a sock-like durable liner/upper topped with a pressure-dispersing breathable tongue.

Safety-oriented house slippers with a light up translucent outsole, glow in the dark band and registration loop, aggressively supportive foam midsole, and extra protection to prevent stubbing toes.

A quick and dirty sketch of a protective sandal designed to mesh stylishly with socks. I chose to approach the shoe from this angle because of the stigmatism around socks and sandals despite their health benefits and/or necessities for most of the people in my user persona.

Design process going from small thumbnail sketches focused on exploration to refined thumbnail sketches before executing the final sketch. What this does not show were the countless hours spent researching competitors, mentally ideating, consulting professionals in the field, receiving feedback during critiques, and everything in-between.

My final concept direction is a supportive slipper that uses a split heel counter design to maintain slip-on capability while drastically improving support and stability.

Outdoor-oriented variant using a boa closure system that tensions the slipper dramatically after sliding the slipper on. This variant uses the same split heel counter design but includes stretchable cord, fabric, and boa line that wraps around the back to lock the heel in permanently after twisting the boa closure. I chose not to move forward with this design because it does not align with my target market and ideal user persona, but I would consider this variant as a future product offered by the Sul brand.
