I have had a bit of a problem with unusual wear on the socks of my 2 drysuits, primarily on the left side, causing leaking. It has happened on my older suit & I sent the suit in to have the socks replaced. Just recently it has happened on my newer suit. These have happened when the suits are about 1-1/2- 2yrs old. Since I will need the suit in a couple of weeks, there is no time to send it back. I was able to seal the worn areas for the time being & hoping it will hold up for my up coming cave diving trip. I am trying to understand why all the wear. Grant it, I'm very flat footed, which causes me to walk on the inside of my foot & when I am wearing my drysuit, I'm pretty much in it all day long. The wear/ leaks occur about an inch above the seam for the sole of the foot along the instep. Anyone else had similar problems? Any way to prevent it?
