text: Purchased these for my husband.  He loved the MuckBoots he got for Christmas 2 years ago, but after constant wearing (think 12 hour days outside on a farm or in the woods) it was time to get new ones.  I purchased these hoping they would be a bit cooler for the summer.  He said they are very comfortable but they aren't any cooler than the last pair of MuckBoots.  Also, the top part of the boot rubbed against his calf for the first week until his lower leg got used to it.  He would order these again.
