Our verdict
The ZeroGrand and Atoms Shoes are close. We gave the ZeroGrand a slight edge at 7/10 over the Atoms Shoes at 6.5/10 — close enough that fit matters more than the score. Amazingly comfortable for all-day wear, but declining quality and sneaker-like styling make Amberjack a better pick for a real dress shoe.

What we liked: Extremely lightweight—about 9 ounces, comparable to sneakers, Shockingly comfortable and well-cushioned, Walk all day without foot fatigue or complaints, Flexible sole that feels natural to move in, Frequently discounted significantly from list price.
Worth knowing: Quality has declined over the years, Reads as a leather sneaker, not a true dress shoe, Full MSRP ($190–$308) is expensive; only worth buying on sale, Some styles and colors are questionably casual for formal settings.

What we liked: Minimalist design pairs with many outfits, Stretch laces cinch tight and stay snug, Vegan and 100% recyclable, Lightweight foam midsole with good cushioning, Wide variety of colorways.
