Useful data points, hopeful for these!
- Familiarity: I returned this product before using it
- Fit: Runs large
- Size Bought: 11.5
I ordered them and have to return for a half size smaller. Here's what should be useful for others:
1) The size 11.5 was almost a full inch longer in the sole than an 11.5 Asolo 520 boot and my other Asolo boots. I'm returning for an 11 and really hoping that it will fit (concerned with the width). 11.5 is my size in two other asolo boots I have which I've hiked extensively in and never had a blister.
2) The weight is phenomenal. One size11.5 boot on an accurate kitchen scale was 2 lbs and half ounce, which is reasonably less that the Asolo 520 which is a hiking boot only. I've weighed my size in the La Sportiva Cubes and the Eiger is 6 ounces less per boot.
3) The tread depth is about 1/2 of that of a La Sportiva Nepal Cube, which probably aligns with the design goal of an ultralight, warm, approach and climbing boot that will more than likely have crampons on it if traction becomes an issue.
I'm scrutinizing boots for a winter ascent of Shasta, likely the Casaval Ridge which is why I'm sweating the ounces and hoping these will be warm enough. I'll update this review if the trip happens. I had to choose a rating (stars) but obviously my rating is somewhat nugatory given I have not hiked in them yet, however I hope this info helps fellow online boot shoppers.
I tried the 1/2 size smaller (11) and the boots are fine from the ball of the foot to the toes (room to wiggle), but from just behind the ball of my foot to the ankles they're definitely too tight. This is a bummer as these are very light and other reviewers say they're pretty warm. The gaiter-esque thing on the boot that covers the laces is a great idea, I really wanted to use these but they just don't fit my feet. Again, I have two pairs of size 11.5 Asolo's that I love and have many miles on them, these are just shaped a little differently and I can tell will be too constrictive of blood flow for me. By the time I size up to relieve that, they're just too long and I think will be a problem going up steep climbs with crampons (for me).
