Every 20 seconds a leg is lost to diabetes. Neuropathy is the most common, costly and deadly complication of diabetes. There are over 450m people living with diabetes worldwide. 90-100% develop nerve damage and lose the ability to feel pain, so a small injury becomes an ulcer, gangrene, and ultimately amputation. Foot ulcers cost the US healthcare system over $80bn/year and are more expensive than any form of cancer. 50% of people lose the other leg within 2 years after a lower-leg amputation. 80% pass away within 5 years. But Siren Socks saves lives. Temperature monitoring is clinically proven to reduce foot ulcers by up to 87.5%. Siren Socks measure the temperature of a patient's feet and along with our team of Siren Nurses and data science team are a fully vertically-integrated solution to diabetic foot management. Instead of waiting to find an oozing wound, all patients have to do is put on their socks like they normally would. A nurse reaches out when there is a potential problem to ask for symptoms and advise them to reduce activity, check their feet and continue wearing Siren Socks. If the injury does not improve over several days or if the patient reports symptoms then the Nurse will reach out the patient’s provider and the provider will decide if the patient needs to come in-person for treatment. Tim White: “You’ve got to be wearing these socks. There’s no alternative.”

Tech Brief

Siren Socks help people with diabetes avoid foot ulcers and amputations. The socks detect temperature, which is an early warning sign of an ulcer. Skin always heats up before it breaks down. The socks are machine washable and do not need to be charged. They turn on and off automatically. Batteries last over a year and socks are automatically replaced after normal wear and tear. A smartphone or internet is not required. All patients need to do is put in their socks and plug in the Siren data hub. That’s it. A team of nurses monitors the patient’s data and calls the patient if there is a potential problem. If the problem persists, the nurses will contact the patient’s provider, who then decides the next step in the patient’s care plan. 40% of people with diabetes can’t feel pain, so a small injury can become an ulcer, gangrene, and ultimately amputation. Time is tissue. Current standard of care is for patients to wear white socks so they can spot the bleeding, or to hope to catch something on a regular doctor visit. Outcomes show this does not work at all (85% of all amputations in the US are preceded by an ulcer). By monitoring temperature, we’re able to catch these injuries early before they turn into life-threatening ulcers. In other words, we give people back the gift of pain. Product video:

Tech Differentiators

Siren offers a comprehensive solution to foot health management and the system has been painstakingly designed to be easy-to-use for all stakeholders: patients, clinical staff and providers. Doctors prescribe by sending an order form. Our support team calls the patient to verify the order and ships it out. All the patient has is put on a pair of Siren Socks and plug in the Siren Hub, that’s it! The Socks automatically connect to the 4G network and send the data to our Siren Nurses. Average setup time is under a minute and our oldest user is 99 years old! The socks are exactly like ordinary socks except our temperature sensors are able to detect potential injuries. Socks are machine washable, do not be charged and are automatically replaced when they wear down. The Socks only turn on and send data when the patient is wear them. If we see no data for a few days, our Nurses will call the patient. Between the teamwork of the Nurses, the Provider and the ease of use of the Sirne Socks, we have been able to achieve an medium wear of 25 days/month with ~85% of patients wears Siren Socks over the 16day/mo threshold required by the Remote Patient Monitoring Other products require smartphones, charging, are not washable, and are not able to achieve the utilization that we have. Doctors who offer multiple products and Siren to their patients, tell us 10/10 patients choose Siren, because it’s easy to understand and easy-to-use.


Temperature monitoring has been proven in multiple NIH-funded large-scale RCTs to reduce the number of ulcers by up to 87.5%. See studies here: Our peer-reviewed evidence shows Siren Socks are reliable and accurate at detecting temperature and the findings match clinical observations. We have submitted multiple other papers that are currently pending review, showing high utilization (median days worn = 25 days per month) and high predictive power (at least 15 days before ulceration) Sharing some patient testimonials: "Siren Socks are the best thing my dad's doctor could have run into. If my dad doesn't follow his doctor's instructions, he could end up with an amputation. I live an hour away from my dad, so when the socks alert, I know that something is going on with his feet and I will drive to him to inspect his feet." - Alisa W. Andrea B.: "I am going on vacation for the first time in years due to Siren Socks. The socks have given me the freedom to get out of the house without worrying about my feet. I get choked up just thinking about what Siren Socks have done for me. I am really excited about being able to make memories with my grandson now." Dr. LaWanna Monday, DPM: "I decided to bring Siren Socks to my practice because it was a no-brainer! Having someone be able to keep an eye on my patients made sense for my practice.“ More doctor testimonials:
