I have had a pair of matterhorn boots about 6-7 years. 10", all leather, vibram soles, gortex liner, cabrelle lining. Durable, comfortable. Kind of heavy at 5lbs but they provide excellent protection to my foot and lower leg.<br><br>The highest boot I had ever worn prior to these was an 8". The first day they felt a little strange. I tried a couple of 8" on after these and they felt short. I love these and am toying with buying a second pair, one for the house, one for the truck.<br><br>I got mine from either US.Cavlary or Brigade Quartermaster. My local mil surplus store carried them but at a higher price.
