This is a really nice shoe: very comfortable and can wear for a long run right out of the box. However, what I found is the toe box is very wide. I have a wide foot and when I laced these up, I found that the lace loops got very close to each other. I also found the material fairly stretch and so the shoe didn't provide much support when running turns. I found the shoe constructed much more like cross between a road racing flat and a road trainer. It is light, but for a trail shoe, this shoe lacks the luggy tread needed for any kind of rugged trail. It also lacks forefoot cushioning and rock plate. These shoes would be good for smooth trails such as a rails to trails trail, but not the rooty, rocky, and some muddy single track forest trails I run in the Finger Lakes upstate NY area.

Confused by the other review - I ran the Pikes Peak Ascent with these shoes this year (the one with the ice and snow and lightning for the last few miles) - these shoes worked perfectly.

Great, light weight shoe. Feels natural on the foot, has good durability, and dries quickly. Ordering another 2 pairs.

Just ordered my second pair of these bad boys. They're light. The mesh uppers keep your feet as cool as possible even the the hot and humid conditions of a Georgia summer. I've put in some long miles on the AT with these shoes any they performed perfectly. I highly recommend. I've got a narrow foot, and these fit perfectly. The only challenge I see with these shoes is the sole due to the fact that the traction isn't as pronounced as some other shoes. that said, I've run some pretty slick/wet trail and have yet to take a dive.

If you are looking for a lightweight trail shoe for this summer, you should give these a try.

The Peak XC's are by far the best pair of running shoes I have ever put on my feet. For the price you can't beat it either. I did my long run (10 miles) two days ago and was so impressed with the over-all comfort and how my feet felt when I was done! The mesh upper kept my feet cool and dry.

You are truly missing out on a great pair of shoes if you don't have these in your closet. Columbus Marathon, here I come!

I run trails and ultras here in the Pacific Northwest. After having my Salomons rip apart while running an ultra in Bend I found the Pearl Izumi Peak XC and haven't looked back.

I weigh 140 lbs and run neutral with a mid foot strike so I look for lighter trail shoes that aren't posted and allow for fast leg turnover. I like a low-riding lightweight shoe for dry/damp conditions and after putting about 300 miles on my pair I have to say that they've held up really well across a whole range of tough conditions are now my preferred dry condition trail shoe. I just used them last weekend for the White River 50 race and they were great. While the tread isn't very deep they are sticky enough and give good traction on rocks, loose dirt, scree and even treacherous roots on some really steep stuff.

Lightweight upper mesh keeps the foot cool and allows water to drain. I use Sof Sole and Arch Mold inserts due to having a high arch. While the Peak XC is not a burly posted shoe for a course like Hard Rock or Cascade Crest, I use them for all my training runs and trail races up to 50 miles. If it's really wet and muddy or really long then I turn to my Montrails. But for at least half the year this is the shoe I use exclusively.

I'm buying another few pairs for my late Summer and early Fall races. Happy feet.

very lite, comfortable shoes. probably the best i have owned yet.

These shoes are light, and are durable. I feel like I am barely wearing anything on my feet. I do have abnormally long toes, and so the toe box is a little tight for me, but as long as my nails are trimmed - no worries! They do well going up and down the hills running or walking. They worked well for me scrambling over sandstone in even muddy conditions.

How can 2 pairs from the same company differ so?? These are maybe the worst pair of shoes that I have ever put on. They were undersized and flimsy is being kind. I want to send them back. Pearl Izumi makes a pair called the syncro float II which is one of the Best shoes I have ever put on my feet. Go figure?
