Great boot!  Can't let you know just yet how long they can be worn since it's still summer and 96 degrees is a bit to warm to wear them yet.  I've purchased many Nine West shoes & boots over the years and have never had any issues so I'm assuming I will have the same experience with these.  Heel is not too high & a platform in the front so not much of a pitch to cause your feet to ache by the end of the day.
