It does an excellent job of focusing on the essentials to help you be your healthiest self.

Fitbit Air review: A fitness pro's impressions after weeks of testing
The Fitbit Air is the latest addition to Google's lineup of popular fitness trackers. And even at first glance, it's clear that this model is a significant pivot from other Fitbits. It's smaller and sleeker, and most notably, it doesn't have a built-in screen. With no display to glance at, the Air is a more passive device than a typical smartwatch.

The Fitbit Air is Google's latest health tracker, and it's a significant pivot from other Fitbits. It's smaller and sleeker, and unlike most wearables, it doesn't have a screen. With no display to glance at your step count or check your pace mid-run, the Air is a more passive device than a typical smartwatch. It's still backed by Fitbit's powerhouse heart rate sensors, tracking software, and newly improved Health app, but this is a distinct left turn from the brand's traditional experience.

These flip-flops for wide feet feel comfortable even after 8 hours of walking
Flip-flops are back again this summer in full Y2K force, and I am here for it. Sliding into these simple sandals instantly feels like peak summer.

They're the best release yet in the Ghost lineup. The Brooks Ghost 16 were our former top overall pick, but they've been usurped by the updated model, the Ghost 17.
