Angaben von Prolimit:
 
The Prolimit hydrogen unisex shoe is the perfect hybrid between a shoe and a boot. The natural rubber reef sole makes you feel like you are walking on bare foots. You can wear the shoes with a shorty to keep your feet warm, but they are also high enough to combine with a winter wetsuit so you skin is covered all the way. The neoprene of the shoes is 3mm thick.
