*_Also, the new guy talks to fast and lacks personality. Great, he is enthusiastic about talking about this, and you see it in his gestures, but just dial it back a bit._*
Highly polished wood panel with similar surface to basketball court. Add weight inside shoe. Tie string to pull loop or otherwise attach to rear of shoe. Add pull scale to end of string. See how many pounds of force before shoe moves.
also could be glass. doesn't have to replicate real world to have comparable data. should prep the shoe and surface with cleaner. and should probably use a shoe "sled" (like a wooden box around the shoe) so the pull point is consistent. if you don't have a last for weight you could use a sock with lead shot that could more easily fill out the shoe, as long as the weight is the same should get interesting data.
8:49 Considering it's the second most common shoe worn by NBA players, I think a better comparison would be a Honda Civic. Incredibly common, practical, unpretentious, works for most ppl. It must work fairly well if so many players wear them; it's not like professional basketball players need to worry abt budget or lack of options when picking shoes.
You want to test shoe sole grip? Try getting a couple of square feet of finished hardwood flooring, placing the shoe on the slab of floor (maybe add some weight to the shoe to “engage” the outsole), and then raising one end of the slab of flooring measure the angle at which the shoe slips down. It might not work, but it would be a repeatable, measurable test.
@@RaccKing21 The angle would need to be >45º, otherwise at 45º an equal component of the weight would be pushing the shoe into the floor as would be pushing it down the slope;
KD have been nothing but a great sneaker line. These are comfy, great traction and cushion and they're far from bulky, which is what you want in a hoop shoe.
Have you even tried wearing these long term especially?? It ages like fine wine. Have played 5 other shoes last year but these shoes are the most fun for me. The more you use it, the better it becomes.
Driving shoes would be interesting. Do F1 drivers have different needs than rally or NASCAR? How do shoes comply with and push the boundaries of the driver apparel specifications?
You have to also remember, that the shoes that the players wear are not the same shoes produced for sale. For example, the actual shoe worn by KD will have full zoom air, whereas the retail one will not. It's one way they are able to sell a cheaper version of the shoe.
6:27 I think you can place a finished piece of plywood, which is kinda similar to a basketball court, on two rollers or wheels and hook it up to some kind of dynamometer on the side. Put the shoe on the plywood, weigh it down by putting something heavy on the inside and then pull it horizontally with some rope or laces towards the side, that is opposite to the dynamometer. The higher the force that is shown on it, the better the traction because shoes with better traction would pull the plywood when pulling the shoe I think that would work, I hope it makes sense
Had a similar idea but instead of pulling it you could tilt the board at a known angle and calculate the coefficient of friction based on the distance it moves, weight of the shoe etc. If they are reading this; just search up “coefficient of friction test method for shoe traction” on google I’m sure you’ll find something.
Kevin durant’s personal shoes are all going to be custom hand made to his specific foot shape and built with much better quality than the mass produced version.
That part! People forget that athletes get theirs custom made. If these are worn by others in the NBA there has to be more to the shoes for them, not the average consumer.
To test gript: put them on the ground and weigh them down with something. Pull them with a newtonmeter (essentially just a spring) untill the shoe starts to move. When grippy shoes start to move, the spring will be extended further than when not so grippy shoes start to move. The amount of spring extention is (in a good setup) a linear function of the grippyness of the shoe. Hope you guys are helpen by my suggestion. I love the channel and have been following since the beginning :)
Glad you guys are getting into other kinds of shoes. IMO you need some kind of rig that has a standard weight that goes in the shoe for giving it some human like drag, then a force scale connected to a pulley that drags the shoe across a controlled surface. You could incline it too if you wanted. You'd want to measure the force it took to make it start moving from static, as well as how well it brings itself to a stop when moving.
Love the shoe breakdowns lately. Way to make the channel even more interesting with the new pivot! I would probably love to see some saddles cut in half next!
surprised you guys dont do running shoes. With carbon fiber plates and insane and expensive types of supercritical super foams, the running shoe space has exploded with tech in the last few years. Shoes are routinely topping out at $250+. Id love to see an analysis and comparison of the makeup and performance of these foams and shoes.
suggestion for grip test: place 50 lbs in shoe, place shoe on hardwood turntable, spin faster and faster until shoe flies out from overcoming centripetal force. You can calculate the force, or just report the rotation speed. Key, you’ll need to test on clean and dusty floor surfaces.
Grip/traction test = tilt test - place the shoe on a board of fixed roughness, raise one side of the board until the shoe loses traction and slides, document angle at which that occurs.
To test grip, maybe a hardwood slip test would work. Take a piece of hardwood flooring (backed by some thick lumber) and lean it up against a wall. Make it an adjustable rig, where you can adjust the angle at which it leans on the wall. Get someone that's average weight to walk/stand on the hardwood and measure the angle to the floor at which he starts to slip. (This is not a standard test, just something I thought of when you mentioned to suggest a test. The idea started with me thinking, "try walking on the wall" but that is physically impossible unless you are Lionel Richie in the "Dancing on the Ceiling" video.)
I’ve always wondered we basketball players don’t get shoes with ankle support ,especially since sprained or rolled ankles is such a common injury. These shoes look like the cheapest thinnest material ,good marketing I guess.
For testing grip: try putting something weighty inside the footwear, the heavier the better. Then put the footwear on the type(s) of surface(s) you wanna test it on, loop some kind of belt/rope around the heel, that’s connected to a machine that measures the force needed to pull the footwear forward. Not exactly the most scientific, but if you can be consist with the weight placed inside the footwear and the surfaces you’re testing on, it should be interesting to start including those tests.
Awesome job man, weston did a great job with his expertise in the leather and shoe costruction environment but you definitely bring it on the next level with your passion and knowledge of the sport keep it up and maybe in the future try to compare old bball(orother sports=models to the new ones
I have at least one pair of KDs per series ever since the 4.. I'm from MD so I always wanted to support. I have floral, aunt pearls, pony hairs, egg nogs, 35k degrees, wtf ect.
Use a basketball court wood plank , add a little weight to the shoe , lift the plank up by degrees and see how steep the the degree is before the shoe slips
To test the grip you may want to take something from car detailing videos where they compare coatings by dragging the shoe across a piece of hardwood court and test how much force it takes to move.
Maybe for testing grip of a shoe you could use a platform which you could change the angle. The idea would be the more steep angle the grippier the shoe. There are some holes in it because high anckle shoes would perform worse in it but maybe it’s a good point to start from and perfect it irl.
To test traction you could put a 5lbs weight in the shoe and then place the show on something like a pane of glass and then a fish-weighing type scale to measure the amount of force for it to slide
I've tried a lot of basketball shoes, having both knees injured, i can say that these pairs are better than the gt jump 2s (bounce and cushion wise). No soreness, good court feel and decent traction.
Try applying weight on to the shoe on a court surface to simulate someone standing in them. Then measure the pull force when trying to pull them forward via the best way to pull forward for this. Maybe looping around the entire shoe or hooking into it. Check out project farm for videos of years that might be able to help with brainstorming.
You could get a squat piece of basketball court and see how high of an angle you can go to until it slips off that would be a good way to test the traction
7:00 yiu could put the shoe on a piece of hard wood and elevate the wood until the shoe slips, tale recorded angle, and degree should be your measurement for grip.
If we say that this shoe is a "Lexus" what would the "Toyota" equivalent be? Or in other words, which low cost shoe hits all the same technical beats or has similar construction with the luxury markups?
I REALLY want to see if anyone can get their hands on a pair of game-worn shoes that a legit NBA player has worn, and compare it to one you buy from a store. I can be almost certain that Nike makes the game worn shoes better than the store bought ones. That'll open up a serious can of worms!
@6:15 can you test the grippyness of climbing shoes? Like LA Sportiva, Black Diamond, Five Ten. They're supposed to be really grippy so you can climb slick spots like sand stone.
Thanks for this new series! You should do a bit more reserch before saying some things so you don't lose you're credibility. First, the signatures shoes as nothing to do with quality, but are all about marketing. That why there are no shoes at the same price in one brand! Before saying that because there is no full-length air is not looking good in fact it not good for a performance basketball. To test the grip you could have the shoes with a weight on a wood floor and test how many pounds of force it takes to push/move it!
