Got a pair of Solutions, and damn, they're pretty tight. I really can't wear them that long. After climbing in them, The tops of my toes had a sort of burning feeling to them.

Are they too small?

How long till they get a little less, painful?

BTW, I know they are not a shoe for comfort.

I bought a pair of Solutions (3 full sizes down from my street shoe in EU sizing) two weeks ago today, so far I've probably used them on 8 occasions for about 20-30 minutes at a time. They are starting to feel like they're breaking in now and are approaching relatively comfortable and less clumpy.

Be patient, wear them around the house for short periods and let them sit near (but not too close!) to a heat source before putting them on, that'll soften them up a bit and ease the pain.
