If you've gone looking for the eufy Smart Sock recently and found nothing in stock, that's not a glitch. The Smart Sock baby monitor has been discontinued, and eufy no longer sells it new. Plenty of parents relied on it, so this post walks through what happened, what it means if you already own one, and which eufy monitors are worth a look if you need a replacement.
What the Smart Sock did
A reminder for anyone who never used one. The Smart Sock was a wearable monitor that slipped onto your baby's foot and tracked the things that are hard to keep an eye on overnight:
Heart rate and blood oxygen, updated to your phone in real time
Sleep patterns and naps, with daily reports and adjustable sensitivity
Alerts when vitals changed, when your baby cried, or when the sock slipped off
A washable fit for babies 0 to 18 months, in three sizes that grew with your little one
Around 24 hours of battery and no subscription fee
The draw was that you could rest a bit easier at night, knowing the numbers were being tracked even when you weren't standing over the crib.
Why it was discontinued
eufy has moved its baby monitoring toward camera-based monitors and away from wearable vitals trackers. Rather than keep the sock going, the team is now focused on the E-series monitors, which cover sleep, sound, and movement through a smart camera.
If vitals tracking was your main reason for buying the sock, that shift probably isn't what you wanted to hear. The section below lays out what the current monitors do and don't cover, so you can judge for yourself instead of being pointed at a swap that isn't really like-for-like.
If you already own a Smart Sock
Discontinuation doesn't switch off the sock you already have. If yours still works, keep using it. eufy continues to support existing owners:
The eufy Baby app and your sleep history still work
Warranty service and support remain available for covered units
Replacement fabric socks and accessories may still be around while stock lasts
The eufy monitors worth switching to
These are the two nursery monitors eufy currently makes. Both use a camera and on-device alerts rather than a wearable, so treat them as a different way to keep watch, not a one-to-one sock replacement.
eufy Baby Monitor E20
The E20 suits most families who just want the essentials. It pairs a 2K HD camera with a 5-inch screen, so you can check on your baby without reaching for your phone.
Hybrid connection that runs with or without Wi-Fi, so an outage or a trip doesn't lock you out
Pan, tilt, and 4X zoom to cover the whole crib
Night vision for the 2am checks
Detection for crying, loud sounds, and room temperature, with alerts sent your way
No monthly fee
eufy Baby Monitor E21
The E21 is the step up for parents who move between rooms, travel often, or just want the sharpest image eufy offers in a nursery camera. It does everything the E20 does and adds more.
4K camera with 8X zoom for the clearest, closest view of the crib
The same hybrid connection that runs with or without Wi-Fi, plus the dedicated monitor
A charging base that keeps the camera easy to dock and power
Night vision for the 2am checks
Detection for crying, loud sounds, and room temperature, with alerts sent your way
No monthly fee
What's different from the Smart Sock
Worth being clear here. The E20 and E21 are camera monitors. They watch and listen well, but they don't measure heart rate or blood oxygen the way the sock did.
So:
If you mainly used the sock to see and hear your baby and catch cry alerts, the E20 or E21 should feel like a step up.
If you bought the sock specifically for vitals, know that eufy's current monitors don't bring that feature back. Many parents switch anyway, but make the call knowing what changes.
For any concern about your baby's breathing, heart rate, or oxygen, talk to your pediatrician. No consumer baby monitor, sock or camera, is a medical device.
How to choose
Lowest price and the essentials? Go with the E20.
Best camera and the most flexibility? Go with the E21.
Counting on heart rate and oxygen readings? Check with your pediatrician about the kind of monitoring that fits before you decide.

Frequently asked questions
Will my Smart Sock keep working now that it's discontinued? Yes. Existing socks still work with the eufy Baby app, and your sleep history stays accessible. Support and warranty service continue for covered units.
Does any eufy monitor track heart rate and oxygen like the sock did? Not right now. The current monitors, the E20 and E21, are camera-based and focus on video, sound, cry detection, and room temperature rather than vitals.
Which replacement should I buy? For most families the E20 covers the essentials at a lower price. Choose the E21 if you want the top camera and the most flexibility. Base it on your budget and how often you travel or move between rooms
