For my next pair. If I can save 500 on pretty much the same performance and comfort in skates, why not.
You'd think 8.5 would be a 9 with toe plugs in the end cap to make it half a size smaller though, not the other way around.
The padding is likely just a thin strip so your toes aren't exposed directly to the carbon she'll and adds some padding. Im pretty sure you got a skate that, like you said, had the wrong tongue put on. If I were you I'd return both skates and order another 8.5. The good news is it's not your mistake and the shop should honor the exchange.
Reach out to them via Instagram or Facebook. The person who handles the social media accounts is really good at replying. Just send him the pictures via either those platforms. I'd suggest Instagram since it looks like it's more active.
