Weezle Extreme Scuba Diving Booties Cold feet are a major complaint of divers. Weezle boots use the same innovative materials as used in our undersuits. The Weezle Extreme scuba diving booties are available in Compact & Extreme Weights. By using the same innovative materials as used in the undersuit, we have not only been able to combat cold feet, but we have taken it one step further. Instead of having an undersuit sock that finishes at the ankle, we have extended it up the leg to just below the knee. This removes that annoying cold spot between the end of the undersuit & the beginning of the sock. Ankle weight wearers will find that this also adds a layer of comfort not featured in other undersuits & long legged people will avoid having a cold gap.
