The best thing since velcro shoelaces?
Both Korkers and Simms have felt the squeeze of the Boa...
Via a press release from Backbone Media:
The Boa Closure System achieves a micro-adjustable, glove-like fit via three key components: a knob, spool, and lace. Turning the high-grip exterior knob activates the internal spool which then pulls the ultra-durable Boa lace with remarkable closure force. The combination of the low-friction lace and lace guides creates a uniform closure that is free from pressure points and automatically conforms to the demands of your feet, activity, and terrain.
Constructed from aircraft grade, stainless steel, the Boa lace is gram-for-gram stronger than tank armor and easily sheds water, mud, ice, or any kind of river muck. Finally, the Boa Closure System is secure: once you set the dial to your desired tension, you're off and don't have to worry about the laces coming untied all day.
