Shoe cubbies were once thought to be confined to the preschool classroom.
Nowadays, you'll find them in the Gusto office in San Francisco, where employees store their shoes while they navigate the workday barefoot or in socks.
Office culture is markedly lax in the West Coast tech hub, and there are a lot of reasons why.
Some have called the region the birthplace of the business casual movement of the late 1980s and 1990s.

The Valley's schtick has always been "discarding norms and celebrating rule-breaking," as The Atlantic reports.
And over time, that hallmark has bled into the work environment as well.
Tech companies famously began instituting office perks like free lunch, nap rooms, and dog-friendly offices.
Gusto and Notion are two startups in the past few years that have offered similar out-of-the-box office practices to workers.

And then when Reeves and a few other techies launched the company in 2011, it was out of a house in Palo Alto.
They all took their shoes off before ascending into the upstairs bedroom-turned-office.
When Gusto moved into a more stable office, the tradition stuck.
The company's employees sprawl out on living room furniture — as well as at desks — sporting slippers or socks. Some are barefoot in the Gusto office.

Zhao told Business Insider that he grew up in a shoeless household as well.
And in lieu of a designated shoe cubby, Notion's office is even more pared-down — employees merely kick them off on the floor near the front door.
Employees saunter around in slippers and socks ...
... and foot cushions are placed beneath their desks.

The shoeless practice is an example of startups crafting their own unique company culture.
There's a high turnover rate at tech companies, and singling your company out in one way or another can help not only recruit, but retain, techies.
On the other hand, some perks that companies offer, like beer on tap and yoga rooms, have been seen as "golden handcuffs" that persuade workers to stay at the office later and work overtime.
Some critics have painted them as more harmful than beneficial to workers as it reinforces the Valley's "work hard/play hard" startup culture.

And some made sure they embraced a healthy culture from the beginning. For Gusto, the company has managed to avoid the fratty company culture often associated with Silicon Valley startups, as Business Insider's Melia Russell writes.
Fortune magazine has named Gusto one of the 100 best workplaces for millennials.
The distinction is likely for a number of factors, but no doubt the cozy office environment and practices are among them.
The company has also earned rave reviews by employees on Glassdoor, with some crediting the company for its "ridiculously generous benefits."

And Notion — besides attracting so much buzz in Silicon Valley's VC scene that investors were literally knocking on the door — has a tight-knit workforce in San Francisco's Mission District.
So maybe they're onto something with bringing the coziness of home into work.
