Caving neoprene socks / wetsocks, perfect caving socks for the caving boots are indispensable in addition to a headlamp, harness, helmets and wetsuit for exploring a cave.
Socks are of great importance to speleologists. Although they spend part of their time hanging from ropes underground or crawling through narrow passages, their feet are still the main means of transport. Very careful attention should be paid to comfortable socks and boots.
For general caving outings, plain wool hiking socks will suffice as they are inexpensive, warm and comfortable. Some cavers opt for the thicker neoprene variant which offers excellent protection in very cold and wet caving conditions. Made from the same material as wetsuits, neoprene socks are much better at keeping your feet warm. The downside is that they are usually more expensive than a good quality pair of hiking socks.
Don't forget to bring your socks when you go shopping for your caving boots - their thickness can affect the size of the boot you should choose.
