  • Love them!!! But..

    May 28, 2018

    These are great! They really are. However, my only wish would be that they were a little more like a true mid-top version of the TR1-Treks in that they incorporated a little more mesh for ventilation as my feet tend to get pretty hot. May not be an issue for you but it does make this shoe sorta useless for me in the warmer months. Through fall and winter though this boot is absolutely fantastic! Way way way comfy!!! And VERSATILE! I travel a lot. Often working in big cities and incorporating outdoor activities when I can. Recently had to work for several days in Toronto, Canada. Decided to road trip it up from North Carolina and spend a couple nights back country camping on the Appalachian Trail in Virginia and Pennsylvania along the way. I like to pack light and this shoe was perfect for both. I could comfortably backpack several miles from the trail head to the nearest lean-to in the AT and also pound the pavement in the city for several days. The low profile is great. When wearing long pants just looks like youre wearing a sneaker, not large obnoxious hiking boots that look completely out of place in an urban environment. Would definitely recommend if you like transitioning from town to trail with quickness and ease.

  • Traipsing onward in these earthly Astral plains . . .

    May 15, 2018

    About a year ago on this site, I raved about a pair of Brewers I'd recently bought, and soon after I purchased another pair of Astrals, this time a pair of Rasslers, which might well be at the moment one of my favorite just slip on w/ loose laces OR get serious and tie-up pairs of canvas shoes -- for a number of reasons I won't go into too much here because those nifty multi-purpose critters are not available anymore on the Astral site. So in my next search for an Astral, I opted for a pair of TR1 Merges, which I like a lot, but they seem to be cut just a tad narrower and shorter than the Rasslers [both are size 10 -- maybe I'll try a size 10 1/2 for the next pair of Merges.] That means thin socks or no socks for the present pair. Either way, the Merges have become a great motorcycle shoe for me, as well as paddling shoe, general light work shoe, and comfortable hiker. And I do appreciate the ankle support being higher in the Merge than the Rassler -- though not enough to give up my ultimately favoring my Rasslers! So bring that shoe back, Astral, please?! Meantime, the sole on the Merge makes for extremely sure and flexible footing -- always a good combination.

    Had my Merges about a month now and I love them. Great for hiking and everyday use. Also great for multi day hike in kayak expeditions. I wear them for everything from work to kayaking and hiking.

  • They run small

    They are nice shoes but they run small. I would maybe recommend ordering a size large.
