It may happen in extreme conditions if water runs into the top cuff of a sock or into the wrist of a glove. So many customers will wear their trousers or leggings over the socks to aviod these conditions. And tuck the cuff under the wrist of the jacket to prevent water running into the glove.
Remember, never submerge your socks or gloves completely. Keep the water level below the cuff of your socks & gloves.
