Can these insoles be trimmed if too big for the shoe? Size says 8-8.5, my shoe is size 8

you can trim it along your original insoles.

Where is size 7 option???

I had to trim the 'toe' of mine

how tall is the arch support exactly? also how well do they hold up to 10+ hours in work boots on concrete?

The arch support is 3cm high. I used to be a teacher. I usually stand 4 hours a day to make lectures. With these insoles, my fatigue relieves a lot. They can help to relive a lot foot pain from long time standing in work boots. They do well to support arches for 8+hours or more. They won't fall easily.

I have a very high arch in my feet, plantar fasciitis and heel spurs. Are these guaranteed to help my issues?

I think this one is good to help relieve foot pain from heel spurs. you can have a try.
