Introduction

Importance of innovative tools in product use is of primary importance to both

consumer and the design industry1

More than 140 million Americans make outdoor recreation a priority and over

$646 billion was spent on outdoor products in 2012.2

Despite progress by industry, 25% of the shoes Americans own are too

uncomfortable to wear3

Comfort factor is claimed to be of utmost importance in wading boots – one of

the most important pieces of angler’s fishing gear4

Anglers commonly prone to sprained or broken ankle due to tumbling into the

river unexpectedly.

Injuries can be prevented by wearing wading boot that provides solid protection with wet, slippery rocks5

Anglers endure safety and fit issues with their footwear because of their unique

conditions posed during fishing

Functional and aesthetical innovations in fastening systems of wading boots

yet unknown and worth in-depth research

Conceptualization of closure systems in

fishing footwear

Literature Reviews

Establish Design Criteria

Initial Problem Area

Goal/Purpose

Activities Output

Types of Fishing Shoes and Boots

Fly fishing- Waterproof, Great Choice for hikers 1

Shore Fishing - High breathability, Great for getting in/off water,

Potential risk for fungus activity, low protection

Boat fishing- Similar to Kayak shoes,

Ideally lightweight, Drains water quickly 3

Canoe and kayak fishing shoes- Designed to quickly drain water,

Lightweight 2

Velcro loosens during wear. Shoe is discarded when the Velcro fails 4

Thus, replacement cost of Velcro is higher than shoelace

Conventional Fastening Systems

Tying laces is time consuming, involves manual dexterity

Lacing loosens, increasing the risk of

tripping 5

performance 6

Buckle & button systems provide a crude discrete circumference

length adjustment

Lacing systems are still preferred closure 7

Shoe closure configurations have not changed over last 50 years 7

Hook/loop, lacing & cleat-based buckles have variable adjustment

Velcro strap system & buckle/ratchet system is mostly

used in Cycling sports 8

Fitting issues

Lacing provides greater strength

than zippers or hook and loop fasteners, but it can cause

pressure on the instep of the foot

User's foot may swell slightly during the course of the day and the

user may accordingly loosen the laces a desired amount to

accommodate the swelling 11

Protection issues

Exposed laces ends may be

stepped on/ become caught/ entangled on another object

Exposed recess for the spring or rigid element would tend to

collect dirt, mud, other debris, thereby increasing the weight of

the footwear 12

Hardware items also tend to catch on other objects on the ground,

thereby causing safety issues

Mobility issues

Buckle, straps or laces require

manipulation by a user, by

loosing or tightening the laces

or by stretching the elastic, to

provide for foot

insertion/retention and/or to

release the foot 13

Concept evaluation

Ideation - Design 1: Buckle with Dial System

Technical Sketch

Inspiration: Helmet & measuring tape

Convenience features:

Dial offers greater degree of micro adjustability

Dial provides fit consistency across the entire shoe- ensures

perfect fit every single time

Padded strap not only holds the threaded mount for passage of

wires, but also evenly spreads pressure across the arch area

No more hassle of loose shoelace ends, as the wires wind up

inside the reel

Tightness can be fine-tuned by dialing in perfect closure force.

Concept Development Phase

Ideation - Design 2: Four-point lock Magnetic Harness

Technical Sketch

Technical Sketch

Convenience features:

Advantages of two tried-and-tested fastening concepts –

Magnetic and Mechanical fastener

Magnetic closure complimented by mechanical locking securely

and reliably fixes the fastener in its closed state.

Magnets are held together securely by attractive force, allowing

for high closure force

Inspiration: Seat Belt

Functioning features:

Use of slidable magnets combined with stable mechanical locking

Opened through lateral sliding

Enables virtually automatic closing by 4 magnetic touch points

2 straps on each side of the shoe has quick release Cam buckle,

which is slided by each tooth

Concept Development Phase

Ideation - Design 3: Tightening Dial System

Technical Sketch

Convenience features:

Independent wings are attached from the bottom side of a

stretchable neoprene liner that offers flexibility and moving space

with apt adjustments

Due to the unique lace guides and precise closure, pressure points

are eliminated

Tightness can be adjusted instantly to dial in the perfect fit every

time

On-the-fly adjustments like this are impossible with shoelaces

Ideation: Positioning of dials to optimize flexibility in fit

adjustments

Functioning features:

Simply loosen the dials and unhook the cables to reroute them and

find the perfect fit

Toe box’s length & width can be adjusted independently with

several ways of lacing for achieving best fit acc. to width and shape

Flexible side and outer “wings” can be adjusted to the foot’s width

and let the anglers fine tune the length with the pull of cable wire

Concept Development Phase

Ideation - Design 4: Calibrating Buckle with Micrometer Gauge

Technical Sketch

Convenience features:

Micrometric closure called “calibrating buckle” ratchets allows

for precise, incremental tightening and loosening of the closure,

for easy on-the-fly micro adjustment

Design allows grit to be cleared easily for reliable function on-

and off-trail

High security Velcro is a double secure closure at the back of

the shoe for further holding back of heel during rigorous

movement activity

Ideation: Attempt to create an ultra-minimalist, yet an innovative

fastening system

Functioning features:

Simple functionality and user interaction describes the uniqueness of

this model

Maximum freedom of flexing with cross over straps all over the foot,

with which one could accommodate all the extensions during the

activity

Push the center button to slightly loosen one tooth at the time; an

outward pull on both side levers completely releases the buckle

Concept Development Phase

Ideation - Design 5: Double Closure system

Cord Lace Inner Closure Zippered Outer Closure

Technical Sketch

Convenience features:

The inside boot closure to focus on comfort and fit and the

outside boot to focus on protection and water resistance

Design allows grit to be cleared easily for reliable function

on- and off-trail

Inner boot are kept snug by a draw cord

Outer shell closes with a zipper and Velcro flap to keep out

the dirt, debris, gravel and mud from the river

Could be a good choice for transition seasons as this model

keeps light snow and water out

Ideation: Integrated gravel guards

Functioning features:

Boot is actually made of an inside boot within an outside boot,

although they cannot be taken apart

Inner boot with traditional cord lace closure, outer boot functions as a

mid-calf gaiter with a zippered closure and a hook-and-loop flap

Inside part has a pull-up for inserting the foot

Concept Selection: Instrument

Opinion rating using a linear 5-point Scale matrix

“Concept 1 is very viable, it also offers the cleanest look and the

easiest entry system.”

“Concept 2 was also interesting, I like the seat belt reference and

the overall ability to be able to customize fit with this design”

“Concept 2 was most interesting, especially the seat belt

reference and the overall ability to be able to customize fit with

this design”

“Concept 2 has an external fixation system and anglers may run

the potential for the fishing line and hooks getting caught on the

loose straps”

“Concept 3 would be my personal favorite and it has infinite

possibilities in its uses and adaptability in fit, comfort and

technical ability.”

“Concept 4 has excellent use of a system with an adjustable

tension and release on a shoe or boot design.”

“Concept 5 utilize a few too many closure systems while workable

requires the wearer to execute too many steps.”

“Most trout fisherman wear waders. These concepts could be a

great solution for surf fishing, could also have some potential for

commercial (long liners, blue fin fishermen, sine netters)”.
