I was looking for Nike Metcons and came across this. There are a number of colours available with limited sizes.
Note: As they are sale items, there are no returns for change of mind. (https://www.thewodlife.com.au/pages/returns)
I'm personally not going to buy them as I don't know my sizing and don't want to risk it, but others might already know their size.
I've never seen these before - what makes you look for these in particular? Are they just everyday runners?
