I was reading a Canadian Running review of the Nike Tempo Next% shoe which is $200 in the US. At the end it says this.

One more note on the stack height, while the men’s shoe comes in at 40 mm, the women’s sits at 42 mm, making it illegal for road competition. If you’re looking to race in this shoe, be sure you’re wearing the men’s version. But if you’re looking for a shoe to help you hammer some hard road workouts or even just get a sidewalk recovery jog done, this is a great option.
And is the men's shoe really lower than the women's or do they have that reversed?
