I bought these because I wanted a lighter shoe for the summer, but still waterproof. I wear the Forclaz 500 boots all day throughout the other seasons and they've been excellent. I wear the Forclaz 600 for hiking and they are all round good, superb in wet conditions.
These shoes, however, seem significantly less breathable than the boots and consequently my feet are getting uncomfortably hot regularly. I find myself reaching for my old sandals instead. Which is a pity. Because I like them and want them to be as trustworthy as the other footwear I've mentioned.
This is a great fitting, sturdy, waterproof shoe that has served me well around the city and on the occasional walk. Sadly, I have found the material on the sole to be slippery when wet. I don't think I could trust them, for example, on wet rocks.
