Fourth Element HALO AR Premium Socks

Inner Space Technology: Incorporating highly advanced thermal technology and one of the most insulating materials ever developed, the HALO A°R socks performance exceeds expectations of any diving sock.
Using technology originally created for space exploration and cryogenics, the HALO A°R socks feature the extreme insulation material A°RGON™ aerogel in a compression resistant matrix.
With phenomenal insulation properties, this material enables the HALO A°R socks to achieve extreme thermal protection from a thinner, less buoyant combination of fabrics. With a wind and water-repellent stretch outer layer, these socks can be worn in total comfort, all day.

The socks feature three layers throughout, and therefore are slightly thicker that the Hotfoot Pro. Order the socks according to your shoe size, rather than the size of the boots on your drysuit, as a snug fit is essential. In some cases, there may not be enough room in your drysuit boot when using the HALO A°R Sock. If you are using an argonaut drysuit, try removing the footbed for a little more room. If you are purchasing a drysuit, we recommend considering sizing your boots one size up, especially if you are at the upper end of a size.
