Unisex sizes range from EUR 36 to 47 (US Men 4 to 13 / Woman 5.5 to 10).

You should buy the model corresponding to your actual foot size.

To be able to connect your sneaker to your smartphone, your device must feature at least Bluetooth 4.0, which is built into devices from Android 4.3 or iPhone 4s at a minimum.

We’ve developed a system that opens the shoes in two ways: a sliding motion will at the same time either close the shoe and tighten its lace, or free the feet while untightening the lace. The motion can easily be controlled via the app, or simply by pressing the button located on the size of your shoe.

We’ve developed algorithms to analyze the different dimensions of a stride: impact force, propulsion level, posture of the foot (pronation/supination), size of your steps, speed, stability, balance, etc. All this information can be measured and analyzed by your shoes, thanks to our tracker and motion sensors.

Your feet can tell a lot about your state of health. Not only do they support your whole body, meaning that any problem in the feet area will have an impact on your entire posture, but they also respond to it. If you have a problem coming from your back for example, you’ll automatically - and often even unconsciously - change the way you stand and walk. Thanks to the knowledge we’ve acquired over the years by working with many experts including podiatrists, we’ve created algorithms that will use and analyze the data collected. Based on this analysis, the shoe will be able to tell if any issue you may have can be treated, corrected, and how.

The Smartshoes are water-resistant and can be worn under the rain without any problems. Of course, with the amount of technology integrated we would recommend avoiding getting them soaked.

We have been able to introduce electronics into the shoe, including a rechargeable battery by induction charging. Basically, a heat-pad inside the front part of the shoe transforms energy from the battery into heat. The temperature is set up and managed by the user via the free smartphone application. A built-in thermostat regulates the overall temperature of each shoe and never exceeds the temperature set-up for your comfort and safety.

The heating area is located in the front of the shoe from the arch forward. In most cases the sensation starts at the extremities - you rarely feel the cold in the heel - this is why we have chosen to heat the front. Thanks to the thermostat, the heating is auto-regulated, which means that the temperature chosen is set in the entire shoe environment.

It takes one to three minutes to reach the desired temperature depending on both the ambient and body temperature along with the type of socks being worn.

Without a charged battery the auto-lacing system will not function. You can recharge you shoes right away with the charger supplied with each perk. Once your shoe is recharged you will be able to open and/or close them within few minutes. If you cannot charge your Smartshoes you can easily remove the tongue manually.

The Smartshoe incorporates a long life Lithium polymer battery in each shoe, individually rechargeable. The battery life per charge depends on use and on the ambient temperature. If you wear your shoes without the heating option, their battery should last a couple weeks. With the heating option on, you can expect a 5-8 hours charge.

The shoes can only be charged with the included charger, which is supplied with the purchase of a pair of Smartshoes.

No. Charging the shoe - even while not fully uncharged - will not damage it.

The shoes should withstand a minimum of 500 cycles.

No, there is no risk of over-charging as the battery will stop charging when it is completely recharged. However, avoid leaving the shoes plugged unnecessarily. When you don’t use the Smartshoe for a long period it is recommended that you periodically charge them to maintain battery life.

We provide a one (1) year limited warranty.

Most people will feel comfortable with a temperature of 30°C / 86°F.

At Digitsole we never compromise the safety of our customers. While designing the Smartshoe, we strove to keep safety paramount and worked hard in making the product extremely robust and most of all, safe.

We’ve added a button on the side of your shoe that you can click on to open or close it. That said, even if you don’t have access to your app, the auto-lacing feature will still function.

In many cases, it is poor blood circulation in tips of your toes that leads to a cold sensation throughout your entire foot. Hence, heating the extremities will facilitate blood circulation and in turn, reduce the sensation of cold. This can help people who regularly have cold feet and those with certain identified diseases like Raynaud’s Syndrome. In these cases, the Smartshoe will definitely improve comfort. However, please note that the Smartshoe is not a medical device. Should you have any concern as to whether you can use this product in your specific condition, please seek proper medical advice.

Batteries are not replaceable, however the type of battery selected will most likely outlive the life of the shoe.

The sneakers are made of leather, microfiber PU and TPU for the upper part, rubber and EVA compounds for the outsole.

With the Bluetooth Technology 4.0.

Connect your shoes to your phone via the free dedicated app by following the instructions. With a simple slide you can control the temperature of each shoe.

No. However, they are available for teenagers with sizes above a men's 4.5 or women's 6.

You can put most insoles in your Smartshoe without hindering the sneakers’ features. However, it depends on the thickness of the said insole.

The battery life depends on how it is used, but approximately 2-3 years.
