Is the water in your booties or in your wetsuit? If it’s in your booties – it’s normal to have some water inside. To avoid water in booties wear tighter booties and booties with straps that help you tighten them and leave less room for water.
f you have water in your wetsuit legs then this means the “seal” between your wetsuit and your booties is very good. Just pull the wetsuit leg with your finger away from the bootie and let the water out every now and then. Also – maybe the problem is also that you get to much water into your wetsuit in the first place?
