Lots of other good reasons for choosing socks:
- Keeps the dirt off the suit if you've been walking over muck
- Keeps the dirt out of the bag
- Suit folds more compactly
- Can use different boots according to the terrain
- Can replace the boots when they rot/wear out
- They're massively better for trim as the socks are tighter
- ... and the suit can be turned inside out to dry.
