ATAN Madisson 3mm Split Toe
 
All natural latex sole and split toe design provides unmatched barefoot feel. 3mm with plush titanium lining make for warmth in conditions down to air and water of 40 degrees Fahrenheit. The fit and feel of these booties is so good they don't need a forefoot / instep strap.
"In 25 years selling windsurfing equipment these are the nicest high cut boots we have ever offered." Isthmus owner - Gary Stone
