Pros
Pro Provides feedback on running technique through voice messages
Sensoria fitness tracker gathers information on how a runner puts pressure on their foot and analyzes it in real-time. If the sock notices something that could potentially cause injuries, it warns the runner with a voice message and suggests a way to improve his technique.
Pro Motivational audio cues
A virtual coach can be set up to congratulate when personal records get beaten, cheer when doing well, and warn when not doing as well as hoped. The frequency of audio cues can be adjusted.

Pro Socks can be washed
Though the fitness tracker is not fully waterproof, the pressure sensitive electronic textile used in the socks can safely be washed and machine dried.
Pro Suits a variety of occasions since it doesn't look like a fitness tracker
The tracker looks more like a regular watch, with a fairly minimal and cleanly designed watch face. You can wear it with many different styles and it will blend in.
Pro Great for people who travel
The tracker uses a battery which means no worrying about bringing charging cords with you, and the battery lasts for up to 8 months.
The time automatically stays synced to your connected smartphone. So when you cross time zones, the Activité Pop will automatically adjust the time for you.
Cons

Con Unreliable altimeter
The socks sometimes have trouble detecting changes in elevation.

Con Only one sock is active at a time
The socks feed data to a single anklet, and information for both feet can't be gathered at the same time yet. This functionality is planned.

Con Doesn't catch some bad running techniques
Currently the fitness tracker covers a relatively small subset of bad running techniques. It's possible to be in a situation where the technique is bad and the device is not aware of it.
Con Very few customization options currently available
Some of the fitness tracker's customization options are planned, but not yet available.
Con Watch bands are low quality and fairly unprofessional in appearance
The overall design makes it feel like there is confusion as to who the target market is for the tracker.
The watch face is sleek and professional in appearance, looking more like a regular watch than a tracker. However the bands available for the watch are made from a cheap-looking silicone. If you wish to buy a replacement band, they are only available in three bright colors (orange, plum, and teal).
Con Sometimes has issues with condensation inside the glass
The watch is supposed to be water resistant up to 50m. However some of the watches have loose backs which causes condensation to build inside the watch, especially after hot showers.
Con Difficult to read in poor lighting
The watch face doesn't have a backlight and the hands don't glow, so it's near impossible to read the time in dark settings without external light.
