Pro Air

I wasn’t sure of the sizing, so contacted customer support, who replied quickly. Shoes arrived quickly. The fit is excellent, as I have wide feet, they are very comfortable and cool for summer riding

I bought these road shoes after being pleased with my Tri-fly triathlon shoes over the last few years but now needed a dedicated pair of road shoes. I thought I knew the size I from the Tri-flys so ordered the same size. However I think these come up bit larger, ether that or they are made on a wider last as the toe section is roomy. It appears that returns are free in Europe (the European distributor seems to be in Belgium) so I would advise ordering your normal size plus one up and one down to bemore sure of getting the right ones.
I did check with the Pearl Izumi chat bot and got this:
Hi Nick!

Returns are free within the first 30 days of purchase. After that, there will be a shipping fee. Just keep in mind that items need to be new, unused, and have their tags attached. We can only accept returns for items purchased within the last 60 days.

The shoes are well made, light and stiff. The double Boas work really well so the fit is great around the heel and ankle with no slipping and good power transmission.
I use Look shoe plates which covered the datum markings on the sole. I had to extend them using a rule and white marker pen to get it right.
The difficulty I encountered, when using the here in the UK summer, is that the are hot. They appear to be well ventilated but the areas of ventilation are small or ineffective. The whole of the inner side of the shoe, from toe to heel, doesn't breathe. And this is dispite it having holes punched inside a
and out! It seems to be a three-ply construction with the centre ply being non-breathing which
makes the hole punching pointless.
For:
Well made, light-weight, great power transmission, easily adjustable. At a bargain price on the sale.
Against:
Runs hot, maybe too hot.

Excellent shoes. True to size.

A high end race shoe who fits very well and can be ajusted very easily with 2 Boa closure system buttons.
The shoe is very well ventilated which will be good for the summer.
