I think the extra mini loop for a chalk bag at the back is great. I think that there are great safety features, such as protection for the bottom loop for clipping in, as well as indicator fabric in the belay loop... when red shows through I buy a new one. It's not heavy and it folds down nicely. I would buy this again in a heartbeat. It's worked out well in the gym as well as for climbing and leading long sandstone routes. Super comfortable.

My only downsides: the gray chin straps on mine are getting really dirty and this seems to hold in a lot of heat. Otherwise would be a 5 star purchase.

I have been climbing in these shoes about once per week in the gym at 5.8-5.11- as well as occasional sandstone/ limestone outdoor climbing. I think the fit is pretty great and I like the liner; it makes things a bit cushier. This is a pretty low volume shoe. I bought these to replace my old Evolv Elektra's that everyone has in the gym. I thought the Evolvs had crappy rubber and I couldn't use my feet for anything. The Sol's have held up well: no signs of wear other than loss of the edge of the shoe, and being able to see where my toes sit on the top of the shoe. The rubber and sole are sticky/ stiff enough that my shoes don't hold me back for the stuff that I do (see above). I have had a great experience with these and really enjoy these moc's.
