  • Filament hardness of approx. 85A
  • Consistent diameter and material properties for reliable, high-quality prints
  • Patented technology enables smooth feeding
  • Low adhesion level and low coefficient of friction for smooth feeding through filament guides
  • High elasticity and excellent abrasion resistance
  • Excellent adhesion to the build platform and between layers
  • REACH and RoHS 2002/95/EC compliant

  • Recommended platform temperature: 30 - 40°C

Frequently Asked Questions (FAQs)

Which extruders are compatible with NinjaFlex?

Extruders that use spring-loaded roller bearings to apply pressure to the extruder drive gear are suitable. Due to the flexibility, the filament must be supported between the drive gear exit and the entrance to the melt chamber.

Is it necessary to coat the build platform with Kapton® tape or hairspray?

NinjaFlex adheres well to most surfaces (including aluminum and glass), so coating the build platform is not necessary. Kapton tape can be used, but the adhesion of the printed part to the tape may be stronger than the tape's adhesion to the build platform.

Does NinjaFlex work well through plastic guide tubes?

Although the surface of NinjaFlex is formulated to reduce friction, using PTFE guide tubes can help further reduce the pull on the extruder.

Is NinjaFlex suitable for food contact?

Although NinjaFlex contains no BPA or other toxins, contact with food is not recommended.

Are there special printer settings that need to be adjusted for NinjaFlex?

NinjaFlex generally works well with similar extruder settings as ABS. Adjusting retraction settings can improve print quality when stopping and starting.

Are there any additional tips for using NinjaFlex?

When switching from another polymer (such as ABS or PLA), the filament should be thoroughly cleaned before starting a print. Use a lower temperature (~180-200°C) when preheating to prevent excess material from flowing out before the print begins.

Are there any safety concerns when using NinjaFlex?

NinjaFlex should be used in a well-ventilated area according to the recommended operating conditions. TPE products can release small amounts of fumes at high temperatures. These fumes are generally considered less harmful than those from ABS, but exposure should still be minimized, especially for sensitive individuals.

Great Fit, Lightweight, and Totally Quiet
Size: 11, Color: New Black05
Great fit and very comfortable once you pick the right size. Lightweight, breathable, and completely silent on hard floors. No squeaks or “suction” sounds like some reviews claimed. Normal packaging, normal opening, no issues at all. Excellent value for the price.

Most comfortable shoes I've ever worn
Size: 11, Color: New Black05
First off, I was not expecting much buying a no-name shoe online, especially for the price. Boy was I in for a surprise... I've owned these for almost a full year, and can confidently say these are the most comfortable shoes I've ever worn. I normally wear a size 11 and these fit me perfectly. Prior to this the most comfortable shoes I had were some Cole Haans with the Nike air technology. These shoes are so lightweight, so comfortable, I can wear them all day long without feeling a thing. Whenever I (rarely) need to wear a different pair of shoes, I am immediately reminded of how much I used to hate wearing shoes and couldn't wait to take them off. Based on the price, I expected them to wear down quickly. However they are still going strong. Running, hiking, long walks, biking, worn to office / casual events. These shoes have been soaked in mud multiple times, but clean up easily by just throwing them in the washing machine and then the dryer. The soles and the insoles have both worn down a bit over the past year; at this rate I expect to get 1.5 to 2 years out of them before needing to be replaced. So far I must have put at least a thousand miles on these shoes based on how much I wear them. They look good too. I have the all-black pair, and they look decent with jeans and a button up shirt for a night out, but also look natural in an athletic setting with shorts and no socks. Very versatile and subtle. Now for the cons, which are minor. The pattern on the bottom of the sole is prone to some squeaking/suction sounds at first. However after about a month some of the ridges wore down just enough that it was no longer a problem. Second: they are not as breathable as I would have liked. For example, when running or biking, you don't feel any air on your feet. Wearing them out in the sun on a hot summer day, your feet will get a bit stuffy. In fact the fabric is woven tight enough that I wear them in the winter and in the rain, and don't get too cold or wet. So I do wish they made a more breathable version for summer time use. All that being said, these are still the best pair of shoes I've ever had. Ultra light weight, comfortable, and can be worn all day long without feeling any fatigue whatsoever. --- UPDATE: It's been 1 year and 9 months, and the soles on these shoes are fully worn out and ready for replacement. Considering I've put between 1,000-2,000 miles of walking in these, that's pretty good. If anyone from Feethit is reading this, here are my top suggestions to perfect this shoe: 1) Easy fix - change the tread pattern. The current pattern causes suction cup effect on hard floors until it starts to wear down. Simply add some gaps in the circle pattern in the tread and it will remedy that issue. 2) Most importantly, put a thin piece of durable rubber on the bottom of the sole. The sole does wear down after some time and lose traction, especially on smooth wet floors (e.g. in the rain, in a kitchen, etc.). A thin piece of durable rubber would add more traction and also extend the life of the cushion-like sole (which is fantastic, don't change it!). This would easily be worth an extra $5-$10 in the price.

Nice shoes, despite the squeak and inconsistent sizing
Size: 12, Color: Black White 05
Excellent shoes at this price point. Quite comfortable. They do tend to have a nasty squeak on tile floors, sort of like a suction cup being engaged and disengaged. I bought the navy blue and went back and bought the black. I have to say that the size varied greatly. With the second pair, I have to be sure to wear thin socks and even then, I struggle to get them on, despite having an extremely narrow foot. I'm not sure that a person with an average width foot could wear them. Buyer beware. You may need to go up a size.

My second pair and what they look like after 2 years
Size: 10.5, Color: New Black05, Size: 10.5, Color: New Black05
I wanted to write a review on these shoes. This is my second purchase. I bought the first pair 2 years ago and the bottoms started wearing out, after all it was 2 years. I read reviews saying that they did not hold up well. My pictures show before and after. The reason I purchased again is because I am impressed with the quality and comfort for the money.
