MerrellMen's Vapor Glove 5 Sneaker

If i wear a 10.5 in nike and a 10 in merrell, should i get these in a 10, or do they run small?

Are these real merrel vapor gloves? I didn’t see this color of vapor glove on their website(US).

How much do they weigh for both shoes together (Size 11)

Can you add an orthotic to the shoe custom or otherwise?
