What happens here

At the Keen quality control lab, various rigorous tests are conducted to ensure durability and safety: 1. **Impact Test:** A steel toe cap is placed in a machine, and a 50-pound weight is dropped onto it from a specified height (equivalent to 101.7 joules of force). The test verifies that the toe cap prevents the internal clay (representing a foot) from being compressed more than half an inch, confirming foot protection. 2. **Waterproofing Flex Test (Keen.Dry Flex Test Machine):** Boots with Keen.Dry waterproof membranes are submerged in red dye and flexed 100,000 times over 2.5 days. Sensors detect any water penetration, and the red dye helps visualize leaks when the boot is cut open, ensuring the membrane remains intact and waterproof. 3. **Eyelet & Lace Test:** A machine pulls an eyelet until either the eyelet or the lace breaks. The force required for failure is recorded, ensuring the strength and integrity of the lacing system.

Goal: Understand the durability and safety tests performed on Keen boots.

Tools and materials

  • Eyelet & Lace Test Machine — Measuring the strength of eyelets and laces
  • Impact Test Machine — Testing the protective capacity of steel toe caps
  • Keen.Dry Waterproof Membrane Keen — The waterproof layer within the boots
  • Safety Glasses — Protecting eyes during testing
  • Steel Toe Cap — Subject to impact testing
  • Waterproofing Flex Test Machine — Testing the integrity of waterproof membranes
  • Clay — Simulating a human foot inside the toe cap for impact testing
  • Red Dye — Visualizing water penetration during waterproofing tests

Okay, so we're going to do our seal toe impact test. This force drop at a force of 101.7 jewels. After the drop, it should the space between the clay and our steel tail should be at less than half an inch. So you you still have your toes? Yes. So here we have our team dry flower flex machine. We test all of our dry boots in here. The red dye is to identify any leaks that may be happening in the waterproof booty. It'll sit here and flex for 100,000 times. 2 and 1/2 days. 2 and 1/2 days. 2 and 1/2 days it does this and the if these machines which have sensors in them register anything it'll stop and at which point we'll go in and cut the cut that is good to see. So then you'll cut it apart to see where you are where you're finding any of your red dye. Now she's getting it set up and all she's going to do is hold that eyelet until either the lace fails or the eyelet fails and then we'll record what that strength is. So that was at 59 kg force. So 59 kilos that's 100 almost 130 lb of force to pull it out. Selene, your job is to randomly go out, pull shoes off from the floor, and destroy them. Yes. Okay. That is my job. And you like your job? I love my job. I've been doing the test of time with them. Meaning that the payer I got last year, I'm still using and abusing. And to this day, I haven't found anything wrong with them. So, when that happens, I like to report back to people and let them know how well they hold up. I hope this video's helped you guys out. Let me know in the comments down below what you want to see next, cuz we've got heavy equipment, we've got power tools, and I think you guys tell me, should I start
