My 10+ year old MTB shoes are finally dying. I'm looking for replacements.

My shoe size is usually 7 UK (42 EU) for the left foot and 7.5 UK (43) for the right.

I see Shimano do European half sizes (under size guide).

Some shoes are available half sizes, others not.

Do you have a pair of Shimano MTB shoes in EU half sizes, and do they make a comfort difference?

Ideally you'd have compared them with full sizes.

Thanks.
