RONALD A hi justin i have no idea why thay are called semi dry. ican say i like them ,they are warmer. they are also completly wet inside when i take them off. sorry ,ido think i would ask the company who makes them that question. ron a master diver naui.
David R iT HAS THE GLIDSKIN INNER SEAL SO IF YOU HAVE THE SUIT THAT HAS THAT AT THE END OF IT, IT SORT OF SEALS OUT THE WATER.
DARRELL B I guess the "semi-dry" label is a marketing tool. The boots are standard wet suit boots. They are of very good quality, probably the best I have ever owned. If matched with their wet suits (that fit very well and let in very little water) they make a good seal and compliment the system. I give them "5" out of 5 for fit, construction, and quality. BTW, I own a Waterproof W2 wet suit, and I also dive a drysuit (with attached boots).
