question: Why do Vans sneakers almost always land face up?
comment: Simply: they have a low center of gravity. Remember the wobbly toys from childhood? They weeble, they wobble, but they don't fall down. Vans are like those. The bottom of the shoe weighs the most, so it is pulled toward earth the strongest. Often, it is pulled strongly enough that it can lift the rest of the shoe a bit. The heavy part ends up on the ground and the lightest part ends up on top.
passages: The Vans challenge is a viral internet challenge that began in March 2019 where people show their Vans shoes landing right-side up after tossing them in the air. The viral sensation reportedly started after a Twitter user shared a video of the occurrence, which was captioned: “Did you know it doesn’t matter how you throw your Vans they will land facing up.” Since then, multiple people on social media posted similar videos of them throwing their Vans in the air and landing right-side up, along with Crocs, UGG boots, and other popular shoes. This theory proved false, as these shoes have not always landed facing up after tossing them.
   The original version of the Vans skateboard logo was designed in Costa Mesa, California in the 1970s by Mark Van Doren at the age of 13. The son of then President and co-owner James Van Doren, Mark designed the logo as a stencil to be spray painted on his skateboards. Initially introduced for the heel tab on an early Vans’ skateboard shoe, the Style 95, this original Vans skateboard logo is an important part of Vans history.”
   Section::::Top types.
  
  The most basic difference in conversion vans is the type of "top". 
  
  Low Tops- Low top vans retain the factory roof on the van. These vans are more aerodynamic, but have less interior space. During the '80s, these vans became less common because TVs, VCRs, and video games that became very popular were also very bulky. With the development of integrated DVDs and flat screen monitors, these vans have recovered somewhat, but they continue to run a distant second to high-topped vans. 
   While the skate shoes design afforded better connection and traction with the deck, skaterboarders themselves could often be identified when wearing the shoes, with Tony Hawk once saying, "If you were wearing Vans shoes in 86, you were a skateboarder" Because of its connection with skateboarding, Vans financed the legendary skateboarding documentary "Dogtown and Z-Boys" and was the first sneaker company to endorse a professional skateboarder Stacy Peralta. Vans has a long history of being a major sponsor of many of skateboarding's competitions and events throughout skateboarding's history as well, including the Vans Warped Tour and the Vans Triple Crown Series.
   Some of the Deutsche Post vans to be replaced by StreetScooters are the Volkswagen Caddy models. StreetScooter showed a larger prototype, the Work L, in September 2016. The Company also announced that it was developing a Work Orange model with an "electro-hydraulic three-way dumper" for use by businesses that deal in trash or construction material handling.
   On March 16, 1966, at 704 East Broadway in Anaheim, California, brothers Paul Van Doren and James Van Doren and Gordon C. Lee opened the first Vans store under the name The Van Doren Rubber Company. The business manufactured shoes and sold them directly to the public. On that first morning, twelve customers purchased Vans deck shoes, which are now known as "Authentic". The company displayed three styles of shoes, which were priced between US$2.49 and US$4.99, but on the opening day, the company had only manufactured display models without any inventory ready to sell—the store rack boxes were actually empty.
   In addition to a Porsche-inspired rear pull tab and visible air the Air Jordan VI was the first Jordan with an inner bootie.
  
  The shoe was retro-ed in 2000, 2002, 2006, 2008–2010, 2012, and 2014–2017.
   In 2009 Vans re-introduced the Cab as part of a twenty-year celebration. It was re-released in the original two colorways offered. In late 2009 the Cab low Vulc was introduced as a low top alternative to the mid.
  
  The shoe is no exception to Vans collaborations with artists, bands, companies, and skate shops and is often released under exclusive colorways by itself, or in pack.

   Vans Half Cab
  
  Vans Half Cab was Steve Caballero's second signature shoe offered from Vans. This shoe came out 3 years after the Caballero. The new generation of skateboarders had been cutting the original Caballero into a mid top to help them perform more dexterous street flip tricks. Vans and Steve Caballero noticed this and decided to offer a mid top version in 1992. Long time and current Vans' employee, Bunny Caminiti, altered the original Vans Caballero pattern to the sloped mid-top that is now known as the Half Cab (Style 33 in Vans' non-sequential numbering system).

   Another type of van, peculiar to North America, is the "step van," so-called because of the ease with which one can step in and out of it. Widely used by delivery services, courier companies and the parcel division of the US Postal Service and Canada Post, they are often seen driven with the door open, especially in big cities. Step vans have more boxy shapes and higher rooftops than other vans, and are rarely employed for carrying passengers.
  
  Section::::Use.:Rollover safety.
   Full-size vans don't usually have off-road suspensions, but their increased body height makes them more prone to tip. Fifteen passenger vans such as the Ford E-Series (at 27.9%), are particularly notorious for rolling over because their height is increased by the heavy-duty suspensions necessary to carry large numbers of people. The rollover tendency is increased when the vehicles are heavily loaded. It is recommended to not load anything on the roof of such vans, and to use drivers experienced or trained in safe operation of the vehicle. In such cases, familiarity with the vehicle's behavior loaded and unloaded, avoiding sudden swerving maneuvers, and reducing speed through tight turns can greatly decrease the rollover risk associated with these vehicles.
   BULLET::::- Stepped/2-step lockers are two-tier lockers, usually available only in 15-inch (38-cm.) width; but the compartments and their doors have an L-shaped cross-section, which causes the division between the doors to follow a zigzag pattern. This configuration enables more hanging height to be included in both upper and lower lockers; but part of each compartment (the lower part of the upper one and the upper part of the lower one) will be only half the usual width of two-tier lockers.
   To use a Vermaport correctly, a customer should position the front end of the shopping cart through the swing-open double doors at the foot of the device and give a push until the cart is engaged by the drive chain. There should be a slight tug if this is done correctly. Once the cart is engaged, the customer boards the adjacent escalator, which travels in parallel with the Vermaport, to the top of the run. Once there, he or she can stand just to the left of the exit doors to wait for the cart to be pushed through.
   Specialised vans are used to redistribute Bicing bicycles between the stations to even out usage patterns. However, as of November 2007, the number and frequency of vans is not able to keep up during the peak hours, making it very difficult to find a spot at which to return the bike in some areas.

   Another method is to mount a pole taller than the entrance, onto the shopping cart, so that the pole will block exit of the cart. However, this method requires that the store aisles be higher than the pole, including lights, piping, any overhead signage and fixtures. It also prevents customers from carting their purchases to their cars in the store's carts. Many customers learn to bring their own folding or otherwise collapsible cart with them, which they can usually hang on the store's cart while shopping.
   Alva started his long relationship working with Vans in 1974, helping to design the off-the-wall skateboard shoe, the original skate shoe. Alva's father had been buying Vans shoes for his kids since they were young. Vans was established in 1966 and was the shoe of choice for the Santa Monica youth culture.
   BULLET::::- Full size rear wheel drive: a full size version, to enable Transit to better replace the outgoing twenty-year-old Econoline/E-Series in the North American market. While the front-wheel drive V347 Transit was sold alongside the E-Series in Mexico starting in 2007 (replacing the Freestar minivan), this generation of the Transit is the first to be officially sold in the United States and Canada. As part of the development cycle, Ford loaned examples of the previous-generation (V347/348) Transit to high-mileage drivers in the United States for evaluation purposes and durability testing.
   The Second Generation ATHLETE built in 2009. The robot was redeveloped and implemented as a corresponding team of two 3 limbed robots, known as Tri-ATHLETs. This advancement allows for better cargo handling and loading and unloading of cargo as the two robots can connect under the cargo dock and separate from each other and lower the cargo at its destination. The second generation ATHLETE stands at a little over 4 m (13 ft) and has a load capacity of 450 kg (990 lb).
   While the S/AS-platform vans did not share direct structural underpinnings with the Chrysler K-Cars, in contrast to their predecessors, the NS vans were the first generation designed from the ground up as a minivan. One of the first Chrysler vehicles designed with CATIA, which allowed for much tighter design tolerances.
   BULLET::::- Half-seats are located near the cab doors for commuters to lean on during peak periods.
  
  Section::::Design.:Retrofits.
   Early Suzuki Carrys are popularly called "half loafs" in South Africa, referring to "half a loaf of bread" (still a staple of many South Africans). In Cape Town and Durban, many of these little vans are seen painted in bright yellow with green artwork and a chopped-off open rear end. These are part of large fleets of privately owned public transport vehicles which fit between normal taxis and city buses. Customers literally hop on the back, and pass the driver a rand or two, and simply jump off at their destination.
  
  BULLET::::- Alternative badges
   The Ford Tourneo Connect, a leisure activity vehicle, is a Transit Connect with side windows and rear seats. All Transit Connects bound for the United States are imported in this configuration to avoid the 25% "chicken tax" on imported light trucks. In 2013, US Customs told Ford that they must stop this practice of importing vans disguised as passenger cars.
