I have been searching for a comfortable mid height boot that I could use season round riding a harley. Was not impressed with the motorcycle branded versions, frankly thought that you paid a lot for a badge and the boot itself was nothing special. Finally found LOWA and wow what a difference this has made. Build quality is excellent, look is clean and the leather liner is awesome. Have been riding in 50 degree weather so I can comment on their suitability in warmer summer weather yet. But so far I love the fit and build quality. Not the cheapest boot but well worth the extra $$.

UPDATE October 1 2012. So it has been several weeks, months since I purchased these boots. In that time I have worn these every day for every purpose. I changed the soles out for super feet  which made these even more comfortable. Absolutely the best shoe I have ever worn. Extremely light weight, great fit, great protection. After months of riding, and moving, yard work, air travel and miles and miles of walking I LOVE these boots. No sign that they are wearing out so I expect I will be still wearing these every day for the next year.
Update May 20 2013.  Continue to wear these boots on a daily basis. Absolutely fantastic fit as they are broken in . Love the stability and light weight. Today I ordered another pair as Amazon has them for $50 off. Figured I will need another set on day. Wear like iron and after one year no signs of wear. Still original strings, all seems tight and leather untattered.
