Rated 5 out of 5 by from So comfortable I wear them every day. I bought a pair of these two years ago (probably the pre-redesign version, but they look just like this) and they are easily the most comfortable shoes I have ever worn. I have never spent this much on a pair of shoes before, but after two years of nearly daily wear, they are holding up great. The treads are a bit worn and the dark finish is worn off the toes and a little on the sides because I treat them roughly. I wish the rubber on the toe went over the top, but the distressed look goes great with a kilt, so no big deal. My biggest complaint is that if you come anywhere near .22 shell casings one is sure to end up lodged in your treads.

Rated 5 out of 5 by from Solid feel, foot protection It took me a few tries to find the perfect boot for me but these boots are it. Extremely well made which results in a very solid feel with maximum protection when hiking over loose stones which is like, always for the trails I hike. This quality construction comes with a little extra cost and weight but the trade-off is more than worth it for me. The boot feels bomb-proof and even after very long hikes over rough terrain your feet feel completely undamaged and not bruised. I had an earlier version of this same boot for a few years but be aware that the sizes are slightly small per US standards. If you are a 13.5 by US standards go with the 14 instead of the 13.

Rated 5 out of 5 by from Great boot, but mislabled I bought a pair of these boots after foot surgery required that I wear the stiffest book I could get. I have never experienced the support and protection these boots provide in my 40+ years of hiking and backpacking. One note, however: Asolo does NOT make a boot with the "GTX" moniker in its name; this is "creative description" on REI's part to let you know the boot is made with Gore Tex (what boot isn't, these days?), and you should go to the manufacturer's site to get the lowdown on this boot. In 2015, Asolo redesigned it, and for the better as far as I can tell. Tough, great traction, and excellent support at the ankle and footbed make this worth the price. Highly recommended, but do your homework.

Rated 5 out of 5 by from Buying second pair tomorrow Headed to REI to buy my second pair of these boots tomorrow. The first pair did wear out. Eventually. I bought my first pair for a trek to Everest base camp. I trained hundreds of miles in them, ascended to base camp and hiked back down. That was in 2011. These boots have put on at least a couple thousand miles since then and were worn as daily construction boots for about 6 months as well. These boots, combined with orange superfeet, are the best most comfortable boots I've ever purchased. Also the cheapest footwear per mile I've ever owned.

Rated 1 out of 5 by from Boot Unreliable for cost - no receipt --no return 3yr old boot. Boots have been cared for, treated, and stored correctly. Tip of the left boot sole began to separate from boot. Recently went for a quick hike, as i am walking on trail I stepped in about an inch of mud. As I pulled out my right boot, sole separated from the boot. Hiked stopped, headed back & right boot b/g to deteriorate quickly. Stepped in a little mud with the left side...front and mid sole separated as well. Contacted Asolo - No Receipt no return. No receipt no repair. POOR Customer Service. Asolo provided a cobler to ship my boots at my expense. To me - its a manufacturers defect. would not purchase the Asolo brand

Rated 5 out of 5 by from Classic, Rugged, and Comfortable This is my second pair of boots. The first pair last me 11 years. I'm 6'4" and 320 lbs. This pair has over 500 miles on them and I hike with a pack weighing about 45 lbs. I've hiked the Inca Trail to Machu Picchu and all over New England this year. These boots handle whatever I throw at them - rock face scrambles, muddy ravine climbs, mountain ascents, and the occasional water crossing. It does not matter if it's 96 degrees or 35 degrees out - my feet always stay comfortable on all day hikes. Set Up: I use the Superfeet Green insoles and 2 pairs of socks (Defeet Woolie Boolie's, Darn Tough Mountain's, Injinj toe socks, or Diluth Trading Company mid-weight wool's).

Rated 1 out of 5 by from What happened Asolo? For over a decade I have bought Asolo TPS 520 EVO hiking boots, but they recently started using much cheaper leather (it got deep scratches and huge chunks knocked off on their first time out, and I wasn't even going off trail*). Also the "wide" isn't any different than their normal pairs (I checked). Even the person at the REI returns verified that people have returned their newer models, and said that her father also complained about the tighter new fits on his "wide" size. * Seriously? I've had previous pair last seasons working in the Alaskan wilderness as an archaeologist, soil scientist, and land rehabilitation technician...and Asolo used to be such an amazing company. :(

Rated 5 out of 5 by from A fantastic boot worth every penny. Asolo hit the spot creating this amazing boot. I started looking for a boots in preparation for a significantly large backpacking trip in Wrangle- St. Elise National park in Alaska. Through glacier streams, snow, rocky moraine, and every condition possible my feet stayed dry warm and incredibly comfortable. I put 50 miles in them before my trip and found they were broken in enough to be comfortable. everyday they get better. Hiking 20 plus miles with a pack I found my feet felt great and well supported. Definitely recommend this boot

Would Obenauf's Heavy Duty LP be a suitable treatment to protect the leather and maintain the weather proof quality of these boots?

Asked by: Vermeer
Yes, the Obenauf's Heavy Duty LP is a fine choice for preserving your leather boots and helping maintain waterproofing.

When Asolo says "few if any" which is it?  Regarding reports of outsole layers seperating?  How many layers in the REI picture above? So REI is ok with the "problem" then if what should never happen does happen, in a year +/-, will REI refund the boots??

Asked by: Dr Alan
Unfortunately, we are unable to quantify the number of delamination reports Asolo may have received. As of October 2016, we have not noted any trends ourselves. The TPS 520 GV Evo has three shock absorbers incorporated in the outsole in high impact areas. These are sandwiched between the outsole layers. If you were to have any issues with delamination, we do offer a satisfaction guarantee:

What is the difference between the wide vs standard fit? Is it just with of the sole or also volume? On a size 42 what is the difference between them?

Asked by: Davis
A wide fit is wider at the ball of the foot, but it is not higher volume. Unfortunately, we do not have a measurement of the difference between a standard width and a wide width in a size 42.

Purchased today (9.24.2016) at REI Eugene the Asolo TPS 520 GV MW. 1. What is the significance of the MW suffix? 2. Reviews here and on Amazon indicate sole problems with some of these boots. Are mine from this lot?

Asked by: Chutney
The MW signifies that it is a Men's Wide shoe. We talked with Asolo, they said they have seen very few, if any reports of soles separating on the new TPS 520 GV Evo. It is possible that the reviews you read were actually about the previous version of this boot (The TPS 520 GV) and were mistakenly submitted to this item page. Having purchased your boots recently, they should not have any quality issues.
