Not true to size,way smaller - Black Diamond Momentum Climbing Shoes - Womens

I was excited to receive these in time to go climbing with some friends but when I tried then on they were way too tight unfortunately. Climbing shoes are supposed to be a bit snug and I got my actual size and they were still like almost 2 sizes too small. I love that they're vegan so I'll be looking for them elsewhere where I can try them in person bc these were final sale and I'm not able to at least exchange for a larger size so I'm stuck with brand new shoes I can't wear,bummer.
