The Boa dial is a patented system that first found favour in snowboard and ski boots. It works by tensioning a superstrong (metal or Kevlar) lace/wire that’s routed through a web pattern on the shoe upper. The benefits are the ability to micro-adjust to a fine level. Boa claims finetuning adjustments of a single millimetre. The low friction and locking means that once you’ve dialled in the fit it stays that way too.
