I finally got a chance to try these out yesterday.
They are 25" long, 30" with the tails, and 8" at their widest point.
They each weigh just under 27 ounces, with the tails at 4.65 ounces, the total with tails is just under two pounds.
I weight 170# and had about 20# of clothes/pack on me. I wore lightweight trail running/orienteering shoes (inov8 oroc 280's) and the binding held them securely. They were comfortable and did not need to be re-adjusted during the hike,
I was only able to get around 6 miles on them yesterday as I had a trekking pole failure and decided to call it a day. I followed some ski tracks through pine forest that had around 3 ft of base and although no fresh powder, was somewhat soft. I also broke trail the last mile out.
The float with the tails was good. I generally dropped a few inches to half a foot and never dropped to a full foot, even with breaking trail over some larger soft banks. I will likely always use the tails at my weight. I was able to add/remove them with gloves on.
They held very well on off-camber stuff and had excellent traction once I reached some open areas with crusty snow and exposed ice. There were no sustained climbs on this route (only 700 ft ascent over the first half of this out and back) so I didn't miss the televator rail.
Overall, they were comfortable with excellent traction and better than expected float. I did find the front binding to be a bit of a pain to adjust, but after adjusting it to my footwear before the hike, I was able to slide and twist to enter and exit them on the trail without needing to re-adjust. I was able to adjust the heel strap on the fly with gloves on. They are very quick to get on and off.
I had planned on trying a few trail offshoots that climb more aggressively, but the trekking pole issue killed that idea. Nonetheless, I am pleased so far, given their performance and light weight at a low price.
If you have any specific questions, fire away.
