Well, I'm not a 8 grade climber, I'm around 6-7, this is just my opinion, just hoping this helps some.
Solutions are great shoes.
It's solid, very solid.
These work great on small edges.
On slab, I needed more friction on surface side rubber but they won't work that way. It's nearly impossible to smear.
Actually it'd be possible if I go one full size up, but then it sacrifices edging I guess...
The thing is most of 6-7 grade problems are not overhang so Solutions are not for mid-level climbers IMHO.
Miuras(not VS version) are better for me for now.
