Are these a 44 or 44.5?
I do not know. Their metric size conversions seem to be screwed up. I ended up with a size 12 but marked 45 on the box.
Generally the size is marked inside the shoe - either under the tongue, or sometimes under the insole. And, occasionally, on the outside bottom of the shoe. I’m very interested in the shoe, but would want to know the exact metric size. For example, I have tried that shoe on in 44 euro and found it a bit too snug. If Specialized makes a 44.5 in this shoe, I’d buy it. If Specialized doesn’t make a 44.5 but does make a 45 which is a legit euro 45, I’m also interested. If you shoes fits one of those categories, I’m interested in your shoes!

Here’s the link to the Trivent sizing:
Specialized Bicycle Components : Equipment - 05 Equip - Shoes - Triathlon
It looks like their 10.5 is a metric 43.5 .

Still have these?
They are long gone. I will delete the listing to avoid confusion.
