FANTASTIC! BUT the dual sided (or double sided) attachment for hard to reach sensitive skin areas is excellent! They are very comfortable and they make my feet look so good! So, my last pair of Nike shoes were Air Icarus back in the early 90s. Oh these are Just lovely! As far as waterproofing goes, I wouldn’t call it water PROOF but it adds a little water resistance. The only issue is the installation similar to some of the reviews I had to twist it slightly so it goes in from both sides. Extremely comfortable. My husband and I installed all the pieces in about 30 minutes using the anchors and screws. The packaging is fancy with cloth fabric package, not regular bubble wrap.
