Editing Wetsuit (section)

====Thermal protection====
In many water sports such as [[scuba diving]], [[surfing]], [[kayaking]], [[windsurfing]], [[sailing]] and even [[fishing]], bootees may be worn to keep the feet warm in the same way that a wetsuit would. Insulation is proportional to thickness and thus to how cold the water which the user can tolerate; it may be above or below the standard of 5–6&nbsp;mm of [[neoprene]]. In warmer climates where the thermal qualities of the bootee are not so important, a bootee with a thickness of 2–3.5&nbsp;mm is common. The leg of the bootee may have a [[zipper]] down one side or may be tightened with a [[velcro]] strap. Where boots are worn with a wetsuit they are usually tucked under the leg of the suit for streamlining, to help hold the zip closed, and to keep foreign objects out.<ref>{{Cite web |last=Doyle |first=Fay |date=2022-12-15 |title=Essential Gear for Cold Water Swimming: As recommended by a year round wild swimmer |url=https://www.thisexpansiveadventure.com/blog/gear-and-equipment/essential-gear-for-cold-water-swimming/ |access-date=2024-10-16 |website=This Expansive Adventure |language=en-US}}</ref>
