I ordered a 1/2 size larger, so they really fit as I expected. However, I marked them as fitting slightly small, so people would know to order a 1/2 size big.

These are great fitting shoes. I have a new pair of Nike Pegasus 36 Trail Runner’s, and I have included a photo of the 2 shoes compared.

First impression is a great fit, but not a lot of cushion. I’m sure I’ll feel every rock. I appreciate that. I’ll be doing some trails in Colorado this summer, so I’ll want to feel where my feet are.

I can’t wait to get on the trails with these!

I saw the post about the 2 loose strings. Both of my shoes have the same, so it must be intentional.

Using these shoes in Northern CA for running in the snow. They are great because my other running shoes fill up with small rocks and slip in the snow. These have nice wide cleats that do not collect rocks and provide excellent traction on the trail. I would say they are about a 1/2 size smaller than my other running shoes but for me that was not an issue. If you are on the fence on sizing I would go up half a size.
