I own this model from TSM. I can confirm it is a double waterloc. And it's a great shoe. Was beating myself up for not getting in on the LS version however long ago and then the same thing popped up on TSM.
The double waterloc is getting a lot of play lately. And people like to tell you you can't topy it, but you absolutely can.
thanks. as i mentioned recently, i purchased the natural cxl chukka from pelle line and they had the double waterloc, which i got topy'd after i almost pulled a hamstring on a wet marble floor. the cobbler mentioned he needed to use a different glue because of the oil in the waterloc sole. no problems so far and it's been a couple of months.
i was always bummed i missed the LS version also, then they popped up at TSM - only problem is i purchased the natural cxl just a couple of months ago. Still unsure if I will keep them, need to compare the two in person to see if i can justify keeping them both.
