The latest word on effective cardio exercise is that you should go for short, intense intervals rather than waste hours on the Stairmaster. Shorter workouts, you say? Good with us, but what about the gear to go with all that? The Airun Plus shoe is designed for the HIIT exerciser who wants to track his BMI and caloric burn rates all the while controlling shoe weight. The built-in Smart Technology controller records BMI and calorie burn results while the weighted insoles can be added or removed based on your needs. Weight and speed information comes from a sensor in the right shoe, while the entire kick is designed with shock absorption and safety in mind. Ready to buy? If you're serious about your body, these things will run you £112.50 ($224) and they come all the way from England.

Remember those cool Nike high-tops that Marty McFly wore in Back to the Future? The ones that laced themselves and you wished you had a pair just like them? If so, listen up: Nike is releasing the Marty McFly 2015's as the Nike Hyperdunks. They won't lace themselves, unfortunately, but will be made of Nike's super light-weight materials. They'll be shilled by Kobe Bryant in black, and we'll be surprised if the Back to the Future roots of these shoes will be shown the light in order to keep the cool young'ns interested, but we all know the truth behind these bitchin' kicks. Hoverboard sold separately.

Just think -- Zappos has been shipping out shoes .9284 minutes after you order them for years with mere humans running the show. Now, your new kicks will likely be at your doorstep moments after you think of ordering them. Said e-tailer has just completed implementation of Kiva Systems' Mobile Fulfillment System, which will see "a fleet of Kiva's mobile robotic drive units and inventory storage pods" hit the company's Shepherdsville, Kentucky facility. The move is being made to keep its distribution system in tip-top shape even with the addition of new products outside of just footwear, and unless some of those mechs grow a mind of their own, we'd say things should pan out just fine.

Personally, we'd prefer slipping our feet into the WiFi-detecting Nike Dunks if given a choice, but it's hard to argue with the smooth factor bundled with the highly customized kicks shown above. Dubbed Illuminated Confusion, the shoes feature a pattern print with "neon green light-up lateral sides that either blink or glow." The lighting on each shoe gets powered by a single AAA cell, and you'll even get a free "custom box" with you order. And considering the $400 price tag and two to three week wait time, we wouldn't expect anything less. Vid after the jump.

We think Heelys could've saved on a few design dollars and just scribbled "mistake" across the bottom of its new Gamer collection of inexplicably Xbox 360-inspired kicks. Maybe that's just us.

Crocs, not unlike Uggs before them, are prime candidates for footware we'd just as well have everyone put back in the closet, especially now that the Japanese National Institute of Technology and Evaluation has apparently issued a public warning regarding the safety of wearing the offensively ugly plastic shoes on escalators. Supposedly some forty people in Japan have been injured wearing the shoes on escalators, including a five year old girl who is said to have lost lost three toenails and suffered a broken toe when her ugly ass shoes got caught in the escalator. Please, Crocs, think of the children -- and everyone else's greater sense of aesthetics.

While we've seen the swoosh used on questionably licensed apparel before, we're fairly certain that a one-off Japanese e-tailer isn't selling a svelte Nike USB flash drive before the company itself with due permissions in place. Nevertheless, users can (well, for the time being, at least) pick the 1GB training shoe USB drive for their Mac or PC, and while it doubles as a keychain or hangs on tight to your Kensington lock port, the real utility is stored beneath the toe. Admittedly, it doesn't look half bad (click through for more proof), but we'd recommend plopping down your ¥2,480 ($20) real quick like before the legal teams return on Monday.

Now that you're packing a cellphone with a vibrating touchscreen, have glasses that rattle your brain if you try to get a bit of shut-eye, and nod your head to the beat of your rumbling headphones, why not put a little shake in your shoes, too? The cleverly named Good Vibrations might sport a website that was probably built in Marky Mark's heyday, but the kicks it sells claim to be therapeutic in nature. The thick-soled shoes feature a non-stick grip, on / off switch, and a rechargeable battery that reportedly provides around five hours of feet shakin' therapy. Designed to massage away the aches and pains throughout the day rather than after the damage is done, these unisex slip-ons are constructed with Spandex, lined with suede, and just might cause fits of laughter if you're the ticklish type. The Good Vibrations shoes are strangely available in just four sizes, leaving most of you with a bit too much (or too little) room inside, but for just about 60 bucks, the fun factor here is probably enough to put aside the fact that they aren't likely to fit.

Just a few days ago, Transformers aficionados were likely elated to see the Optimus Prime iPod speaker dock, and now we've got one more option for you to add to your collection. Not too long after learning a few secretive details about the Nike Speed+ watch, now it seems that Convoy and Megatron are busting out of a pair of Nike Free 7.0 kicks, ready to rock and lace up their enemie. As the first two members of the Transformers Sports Label series, these items are actually half scale renditions of life-sized footwear, measuring around 6-inches in length but reportedly featuring all the same qualities of an actual Nike shoe. Interestingly, the two bots even rock a diminutive pair of Nike Free shoes themselves, but there's no word on if wearing these things actually gives you similar powers. Nevertheless, the inseparable set should start shipping by May, and while the standard edition will set you back $58.99, you might as well spring for the "Collector's Grade" for an extra four bucks.

It seems like Sayo Isaac Daniel has some serious competition coming at him in the GPS shoe market, as GTX Corporation is unveiling its latest geo-tracking footwear at next week's World Shoe Association trade show. The questionably styled Xplorer kicks pack an internal GPS transceiver, built-in battery that's good for "several days" before needing a recharge, and a sleek Dual GeoFencing feature that keeps your offspring on a leash gives parents peace of mind. Shoe owners (read: paranoid guardians) can utilize the firm's "internet portal" in order to pinpoint limited boundaries in which the wearer can, um, Xplore, and if the person's shoes ever leave the pre-set area, a phone alert will be immediately sent to a pre-selected individual to warn them. No pricing or release information was readily available, but if we had to guess, we doubt your kiddo will be begging for these next school year anyway.

We've seen some fairly interesting means of keeping track of your mischievous kids (or pets), but Sayo Isaac Daniel's latest invention takes top honors as the ultimate paranoid parent's must-have gizmo. Aside from the obvious tracking uses, Daniel's GPS footwear is actually intended to beam out a distress signal to a pre-selected recipient if the wearer hits a certain panic button. The GPS-equipped kicks would present the location of the violated victim to whoever is deemed that person's hero, and would hopefully give the rescuer enough time to arrive and lay down the law. Also, the patent explains an "alarm toe switch" that would be inserted within the shoe in order to give customers the ability to sound their alarm (intentionally or otherwise) without making any sudden movements. Reportedly, a company dubbed Quantum Satellite Technology plans to start selling the shoes "in March for around $350 per pair," but the GPS signal emanating from your soles won't do you much good if your kidnapper ditches your footwear before tossing you in the trunk.

Now if they could only figure out Power Lacing Technology. California-based Outland Research has recently received a patent for its new sports shoe tech that allows for adjustable cushioning. The shoe features multiple hollow bladders, which are connected by a series of tubes (just like the internet) and contain some spiffy electrically-activated liquid. When a charge is applied, the liquid hardens, changing from a free-flowing cushion to a stiff foot support for running or jogging. The change can be activated by a knob on the shoe, via Bluetooth, or even potentially by a shock sensor in the shoe itself, which could adjust firmness on the fly. Changes in the liquid take only a few milliseconds, so the shoe could even potentially adjust stiffness step to step. No word yet on any commercial takers just yet.

While already popular in Clarks shoe stores across the UK, QinetiQ's 3D foot gauge is finally making its way across the pond. Unveiled in three Boston Stride Rite locations, these trials are slated to lead to a more widespread release across the chain's 450 American locations, giving shoe-wanting citizens "quick and accurate" measurements when sizing up. The contraption features six 3D digital cameras that scan the foot to provided "highly detailed length, girth, and shape data," essentially helping to ensure the best fit possible. Additionally, recorded 3D data can enable trend analysis, which would assist in designing future styles and improving stock control. The optical ranging technology used in the device was actually derived from work done on the "detection of unexploded ordnance" for the UK's Ministry of Defense. Although we're unsure how quickly these things will roll out nationwide, we're sure QinetiQ stands to make a hefty sum from its invention, as its current deal with Clarks yielded a whopping £4.6 million ($9.1 million) over in England.

While neither can match the simple geek elegance of street artist Invader's Space Invader-themed kicks, Nintendo and Sony fanboys now have some sneakers of their own to covet, although both look to be harder to get your hands on than a Wii or PS3. Sony's the only one of the two to get official with its sneaks, partnering with Nike for some PlayStation 3-themed footwear (at least that's what they're sayin' -- from the looks of it, Nike may have just taken the opportunity to unload some rejected designs.) Only 24 pairs of the PS3 sneaks were made, with most no doubt spoken for by now. You won't fare any better with the Nintendo shoes, however; these stylish but apparently non-functional kicks being strictly one of a kind, created by an talented sneaker artist for a recent Sneakerpimps event in Baltimore.
