Altras for rock scrambling - bad idea?

For hiking/backpacking, I've recently switched over to Altras (lone peak 4) and absolutely love them!   I'm doing a couple Sierra routes (Mt. Emerson and Clyde Minaret) next weekend and am debating if I should bring my Altras for rock scrambling on the approach, descent, and the easy 5th class ridge climbing instead of my heavier approach shoes (I have an old pair of Scarpa Crux).    I'm assuming the wide toe box would make 5.0 feel like 5.9 but does anybody have any positive experiences with Altras on rock terrain?  Thanks!

They are really soft and not very sticky.

If you have Altra feet, the Five Ten Camp 4 and Camp 4 Mid are much stickier, much firmer and have an edge to climb on if you need. 

Altra is releasing approach shoes

Check these out, I just got a pair but haven't taken them for a spin yet:

I sometimes use my Lone Peaks and Superiors to scramble around J Tree, pretty taxing on the foot muscles. Graftons have Vibram XS Trek rubber.

Lack of lateral support makes off camber steps real ankle rollers

Too soft. I've climbed 5.8 in them and the feet were not confidence inspiring. I was basically campusing.

 But for 5- they work fine.

What model are you referencing? Lone Peaks or an approach style model

The ones the OP was asking about. LP4s.
