Orvis Orvis BOA M4 Repair Kit

The complete BOA M4 repair kit includes everything you need to fully restore the lacing system of your Orvis wading shoes: a replacement wheel and a 100 or 110cm cable, suitable for sizes 41 to 47. An economical and immediate solution to avoid replacing a pair of shoes still in good condition.

This all-in-one kit includes the two essential components of the BOA system:

• The adjustment wheel (BOA disc): the central part of the mechanism, it ensures the winding of the cable and the gradual tightening of the shoe around the foot. In case of breakage or deterioration of the ratchet, it is the one to replace first.
• The 100 cm cable: the BOA cable is subject to repeated strains — traction, humidity, rubbing on rocks. Over time, it can deform, fray or break. This kit allows you to replace it at the same time as the wheel for a completely renewed system.

When the wheel loosens, the cable has often undergone the same strains and shows signs of fatigue. Replacing both elements simultaneously is the guarantee of a completely reliable and consistent BOA system, without risk of cable breakage a few weeks later. It is also the most rational choice in terms of quality/durability ratio.

The 100 cm cable provided in this kit is sized for wading shoes in sizes 41 to 43, the 110cm one for sizes 45 to 47. Before ordering, check that your size is within this range and that your shoes are equipped with the BOA lacing system — identifiable by its characteristic rotary wheel.

This kit is compatible with shoe models incorporating a standard BOA system. If in doubt about compatibility with your specific model, do not hesitate to contact us.
