★BURTON Boots Speed Zone One Foot ①★ One used foot of the upper and lower Speed Zone lacing system. The upper is approximately 94cm long, and the lower is approximately 81cm long, measured to the double part near the handle. This was originally attached to a Burton SLX boot, size 25cm, but the length should be the same regardless of boot size. I think it's still usable, but please judge the condition from the photos. Would be good as a spare, in case your current one breaks.
