ION Ballistic Socks 6/5 Internal Split 2.0

Exceptional Warmth and Maximum Protection for Harsh Conditions.

The ION Ballistic Socks 6/5 Internal Split (IS) are built to face the harshest winter conditions without sacrificing the precision of your board feel. As part of ION's premium footwear line, these 6/5mm socks combine the "bullet-proof" protection of an Aramid (Kevlar) sole with the high-tech warmth of Plasma_Plush 2.0 . For 2026, they remain the gold standard for riders who need to survive freezing water temperatures (2°C–7°C) while maintaining a "locked-in" feel for technical foiling.

In ION's cold-water accessories range, the Ballistic name points to the more protective, more rugged end of the line-up. Choose it if you ride harder, launch off rough ground, or simply want something that feels more robust under regular use.

Why choose the ION Ballistic Socks 6/5 Internal Split 2.0

FAQs

This is best suited to riders who want to extend their comfort window in cooler water and wind without jumping straight to the bulkiest option available.

Not always. The right choice depends on your local conditions, how cold you personally get, and how much board feel or dexterity you want to keep. Many riders are better off with the lightest option that still keeps them comfortable.
