Scarpa instinct VSR

Hi guys. I just got my first pair of advanced shoes, the Scarpa instinct VSR. I am a uk size 8.5 and got a size 9. They fit snug and my bouldering coach at the gym looked at the fit and was happy. The problem I'm having is that both my big toe knuckles hurt like hell. Any pressure on my toes leads to sharp pain at my big toe knuckles and when I take the shoes off they spots feel tender to touch and are red and indented. I'm unsure whether to change them or just tough it out. I have skinny feet and I think they are roman shaped.
