Product overview

About this product

The Ocean Hunter Fin Sock 3.5mm is a neoprene spearfishing sock made for divers who want additional insulation and foot protection in colder conditions. Its 3.5mm construction provides clearly specified coverage around the foot and ankle.

The soft construction adds warmth and comfort around the foot, while a patterned underfoot section helps reduce slipping where the sock contacts a surface. It remains a soft fin sock rather than a hard-sole boot.

Ocean Hunter's general guidance places fin socks mainly inside closed-heel fins. They may also be worn inside a hard-sole dive boot when using open-heel fins, giving the sock a defined role in either supported equipment arrangement.

Product guidance

Choosing and caring for your gear

The 3.5mm thickness is the key distinction for this model. Ocean Hunter positions the thicker neoprene for additional insulation and protection in colder conditions, but does not publish a quantified temperature range. Use the stated EU and US conversions as the starting point for size selection.
