It runs the gamut here from traditional hiking boots, to trail runners, to hiking sandals. And, it depends on what kind of hiking/backpacking you intend to do and the terrain in which you plan to do it in. Is that a vague enough answer?
I've had good luck with Merrill's Ventilators.
If you've had good experience with Asolo and like the weight, then stick with what you know. Just make sure the newest models have the same lasts (form design) as the ones you wear now.
Company's change them from year to year and it really screws things up.
If you think you can, you can. If you think you can't, you can't. Either way, you're right.
