Not sure how useful thoughts on a cycling shoe is, but here you go.
Background: I ride 5 times or more a week. 2-3 of those times are spent on the trainer due to the current pandemic. I have owned a lot of cycling shoes for both road and dirt. I have only owned two non-carbon soled shoes before this.
Got my SuperRep Cycles a little over a week ago. Put them through a short spin on my bike the day I got them setting up the cleat fit. After that, I put in a few trainer rides.
Style wise, they look great IMO. Materials on the upper are really nice and feel premium.
Mounting cleats is hilarious. While I think it is genius the way they built a dual style mounting system that can be swapped out easily, there are no markings for cleat alignment. Have fun mirroring the cleat points on both shoes.
Fit is meh. The strap at the ball of the feet is pointless, as in most cycling cleats. I have to really pull the upper strap hard to get locked in at the heel the way I like. Velcro straps are Nike's way to save costs and keep it a quick on and off experience.
In the pic below, you might be able to see how tight the top strap is vs. how loose the rest of the shoe is. This could be attributed to foot shape. However, this would be the first cycling shoe I have had fit like cinched down mom jeans.
The shoes run slightly short on my normal 12.5 Nike sizing. Not a big deal since I tend to only spend an hour and a half or less on the trainer at a time. I would size up by .5 for long rides. Widthwise, there is plenty of volume upfront. It was nice to have some breathing room when the feet started to swell.
Above the arch feels loose, no matter what I do to ratchet up down the fit. You can see the excess material wrinkling below. It's sloppy.
Performance is pretty lackluster TBH. The outsole needs to be as stiff as possible and nylon itself is flexible by nature. Carbon will improve this instantly but increases the cost just as much. Inside, there is a single piece of nylon that is hallowed out in a grid of plastic. It looks stiff, but it isn't.
Breaking the outsole into three pieces is going in the wrong direction and I can feel the pressure on my midfoot. If I get out of the saddle to throw down some power, the pressure is pretty annoying and almost painful.
Ventilation was what I expected to blow me away. It didn't. This shoe is aimed at spin classes and indoor training. In my pain cave, I have a fan at my foot level that blows towards me. I couldn't tell a difference between these and other ventilated cycling shoes I own.
There's really no reason to own these other than getting a pair of cycling shoes with a swoosh on them. For the money, you can get a number of other entry-level cycling shoes that will breathe as well but perform way better when pedaling. Fit will be nicer and mounting cleats won't be an issue.
