Endorphin Speed 4 Killer?
Overall: If you need a speed focused super trainer/entry race shoe, I think these are a great budget yet quality option especially if you want to try a Chinese brand.Uppers: Lightweight, extremely breathable, 1 to 1 fit, Great lockdown. Minimal upper that offers enough support.Midsole: Bouncy, responsive without compromising comfort. I don't think you can get any western brand with this type of dual purpose "super foam" compound without going into the close to the $200 range.Outsole: Have not taken it out for a full run due to illness but no nonsense, full coverage rubber that has a certain stickiness.Caution: Ensure you reference the sizing chart, I had to size up from my usual 10 to 10.5, there's a bit extra room from the end of the shoe due to their weird sizing at 10 and 10.5 but I'm okay with more the extra bit of length doesn't effect fit very much.Update #1: Went TTS going to keep the one that fits better. Will updated with more information when they arrive.

Super light and bouncy
Excellent training/race shoe. Very, very bouncy foam and carbon fiber plate with great energy return. Super light. Probably only for those with a relatively neutral stride, as there is not a lot of stability built in. Fits true to size.

Satisfied
This shoe meets my expectations as a light cushioned responsive trainer/racer. My goal is to run easy to slightly moderate pace in neighborhoods taking frequent sharp corners. The traction has met my needs for that purpose. I found the fit to be just right throughout the foot with no hotspots and enough wiggle room in toebox. While the foam is soft enough and springy, I did swap out the original insole, which is glued in, with a thicker one for better shock protection. I am very pleased with this shoe. Great value.

Elevate Your Running Experience With These Lightweight Wonders
If you're on the hunt for a pair of sneakers that feel like an extension of your feet, the Feidian 5 Challenger might just be your perfect match. I've been using them for a few weeks now, and they've completely transformed my running sessions. From the moment I laced them up, I felt an immediate comfort that only seemed to enhance with each run. The standout feature for me is the incredible lightweight feel, thanks to the innovative midsole technology. You know that sensation when you feel like you're almost floating? That's what running in these shoes feels like. The BOOM technology really lives up to its name, offering fantastic rebound performance that gives you a little extra spring in your step, especially useful during those long runs when fatigue starts to set in. What I also admire about these sneakers is their durability. The BOOM FIBER technology in the upper material is not just a fancy name. It genuinely holds up well, providing a snug yet breathable fit, and it hasn't shown any signs of wear or deformation despite my vigorous running routine. The added bonus is the carbon-fiber plate, which offers superb support and helps with energy transfer. It's like having a little extra push with every stride. Lastly, the Ground Control Rubber is a game-changer for those who run on varied surfaces. The grip is outstanding, even on wet terrain, which gives me peace of mind knowing that slips and falls are a thing of the past. If you're serious about running and want a shoe that combines innovation, comfort, and safety, these sneakers are definitely worth a try.

Fast out the box
Best carbon plate running shoes I've ever owned. These shoes just scream fast. I've already received compliments from the design and color. These shoes are extremely durable for a carbon shoe. I don't want to run in anything else; this is after I have spent hundreds/thousands on various nikes, adidas, and asics top running shoes.
