I have gone through several deep water crossings and had no problems, but I also applied sno-seal to the stitching to keep it from leaking. The boots themselves are bombproof. Lots of protection and comfortable enough to walk in so far. They aren't low key though. They are full on off road boots and look like it. I got the black ones and they don't stand out too much. The buckles seem really well done. They are almost as nice as SIDI buckles.

My previous Toucans lasted 12 months (heavy every day use during my RTW).
For comparison, Sidi Adventure boots lasted only 6 months.
If I would buy new Toucans now, I would still buy old version (with different buckles) and the best part is that they are cheaper than new version.
