I've been looking at boots and thinking about getting a pair of hot weather boots for hot weather use.

But, are they really very much cooler than old-fashioned leather army boots?

Seems like they might be worse in that the ones I've handled in the stores seem to be just as thickly insulated as the chinese import "combat" boots (Converse) I already have which turn my feet to soft soggy messes even in cool weather.

My feet seem happier in full leather than nylon. Even street shoes vs sneakers gives me drier feet.

Advice or experience please?
