The Billabong 5mm Absolute Neoprene Boots benefit from the split toe sytem which makes them very flexible.
The round toe system provides more warmth, by having all the toes together. With 5mm thickness and sealed seams, the Billabong Furnace Boot are perfect neoprene booties for surfing the coldest days of the year.
