One of the gear questions I get asked most often is whether or not a person should opt for the Boa closure system on their new wading boots. Boa laces are wire and they crank tight by turning a knob at the top of the boot. Pull the knob, the wire loosens, and you step right out of the boot. The idea had been successfully applied to ski boots, and Korkers was the first to get a license to use Boa on wading boots a few years ago. In recent years, many other boot manufacturers have fallen in line, not wanting to give up market share by not offering this feature. The effect on price really isn't significant. It usually comes down to a matter of personal preference. I know people who swear by Boa, and some who hate it.
