These are very lightweight and fairly roomy in the toe box area, for those with wider feet, which I welcome.  However, I was expecting them to be a bit more breathable (by the looks of them) and cooler.  They are clearly much warmer than the now discontinued Columbia Redmond Breeze due to the padding material in the venting slots.  Depending on what you're looking for this may be good or bad.  Also, a bit expensive.
