KEENWomen's Targhee 3 Waterproof Hiking Shoe

I have an older pair of Keen low hikers, different model too, but a negative is their lack of grip on wet surfaces. How does this hiker do on wet?

Does anyone find these shoes make your feet feel really hot?

Are these walking shoes true to size? I have wide get so not sure whether i should go up half a size.

I bought these in october and even though they have not been used that much, they leak badly. Is this usual?
