Dang, wearing out a set of Kenetrek souls a year is alotta rough walking, How may times did you re-sole those boots before they failed? Sounds like maybe those boots gave their all and then some. Hard to be ****ed at the breeder cause your horse died of old age no matter how many times you had to shoe him. If you liked your Mountain Extremes, good luck finding a boot you will like as well or that will last as long under the same conditions. Boots are a consumable and feet are important. Now you know, re-sole em once and replace. Take a look at the Mountain Guide. A little heavier than the Extremes, but they do stand up to rock and scree noticeably better.
