Jim, I have worn the old aquastealth as well as plain old rubber flats shoes on the beach and have never found any big difference with felt. The new Orvis shoes have a different tread pattern than Simms that has been tested thoroughly (not by me as they just came in). They come with "opt out" studs. They are not removeable or interchangeable.Leland - are these soles the same as others (i.e. Simms) is now using or is that a secret?
Have you test waded and compared to felt in streams and seaweed covered beaches?
Do you know if these soles can be put on a boot that has felt (after removing felt of course). I asked a guy in a fly shop if Simms could do that he said not at this time (some months ago). Two factors were glue formula and availability of the vibram soles from manufacturing.
I have a pair of getting on in their age Simms (that I got a great deal on at your shop) and they will need new felt soon so look at options. New boots entirely is one option.
You should see how worn mine are. I can see the undersole showing through.Thanks. I am going to try to stop by to check it out. Probably wait for the next "event" mid Feb. Once felt gets worn down it has a hella of lot less stick-em. I took a hard fall last summer when my smoothed over, alien infested felt became as slick as deer guts on a door knob (I am still trying to figure out who came up with that saying) on a big flat rock and I ended up face first in a creek. Been thinking about switching over since.
