No-Tie Lace System Design Proposal
CONFIDENTIAL DOCUMENT | Ryan McMahon | (971) 219-5555 | [email protected] | ryanmcmahon.org
Needs Addressed
• Laces hard to tie when under high tension
• Difficult to get correct lace tension
• Cold hands make tying even harder
• Frequent adjustment not practical with tied laces – especially when using double-knots CONFIDENTIAL DOCUMENT | Ryan McMahon | (971) 219-5555 | [email protected] | ryanmcmahon.org
System Description
Left lace in bottom groove
Right lace in top groove
Laces slide freely in one direction and lock in groove when released

Usage
• Start day—loose laces for increased comfort
• Top of run—tighten laces to optimum riding tension (with gloves on!)
• When needed—release laces and adjust tension
• Bottom of run—loosen laces for chair ride or hiking

Robust Design
• Intuitive design
• Easy to use
• Laces pull in opposing directions in equal force to minimize stress placed on joint between component and boot tongue
