COASIS Women’s Chunky Block Heels Open Toe Ankle Strap 3.5-Inch Heeled Sandals
Product description
Key takeaways
If you’re after a dressier sandal that still feels steady, COASIS chunky block heels are built around that idea. With a 3.5-inch heel and an open-toe, ankle-strap design, they aim to give you height and a more secure feel than a lot of thinner-heeled options. The rubber sole and the platform height (about 0.25") are there to support everyday walking, not just photos.
That said, comfort is always a little personal. “Soft” cushioning helps, but if you’re extremely sensitive underfoot or you’re planning long hours on hard flooring, it may not feel perfect for everyone. On paper, it’s a practical choice for outings, events, and a night out.
The essentials

These are women’s heeled sandals with an open toe, a chunky block heel, and an ankle strap meant for a more locked-in fit. The design is positioned as a do-it-all pair: weddings, work, date nights, homecoming parties, and also regular daily wear with different outfits.
The overall concept is pretty clear: keep the look of a heel, but use a wider base and platform to make steps feel easier to manage. It’s the kind of heel you can actually wear beyond “one quick stop,” assuming your usual comfort tolerance matches the height.
What stands out in use


The rubber outsole is described as wear-resistant and non-slip, which matters when you’re walking on smooth sidewalks, parking lots, or event venues where surfaces vary. The block heel plus platform also does a lot of the heavy lifting for stability—this is where these tend to feel more beginner-friendly than sleek stiletto shapes.

For comfort, the midsole uses soft latex (3 mm) and there’s a PU insole designed to follow the natural curve of your foot. In real-life terms, that translates to less “all pressure on the ball of your foot” feeling than you might get from harder footbeds—especially when you’re moving around during an event.
Is it magic? No. Chunky heels can still feel like heels after a while, and the open-toe design won’t change that. But if you want a more forgiving walking experience, this is the direction they’re taking.

Who it’s for (and who should skip it)
It makes sense if you want a stable heeled sandal with an ankle strap, and you’re shopping for something that can handle both special occasions and regular wear. You’ll likely appreciate it if you prefer a solid base underfoot and want a more secure step when you’re walking longer than “just to the car.”


It might not be a great match if you need a very cushioned, supportive shoe for all-day comfort regardless of heel height, or if you typically find 3.5" heels too demanding. Also, if you’re extremely particular about fit details (strap placement and how it locks your foot in), you may want to pay extra attention before committing, since the provided info doesn’t spell out width options or sizing guidance.
Getting the most from it

A quick, practical way to evaluate these on arrival: wear them around your home for a short stretch while paying attention to two things—how the ankle strap feels during movement, and whether you notice any pressure hotspots after a few minutes. If the strap feels too tight (or too loose) early on, that’s usually a sign the pair won’t magically become comfortable later.
Also consider where you’ll wear them most. For weddings, homecoming, or work events, the platform and block heel design should help you keep your stride. For very rough or unpredictable surfaces, no sandal is fully risk-free, even with a non-slip outsole—so use common sense.
Is it worth it?
Buy these COASIS chunky block heels if you want an open-toe, ankle-strap sandal with a 3.5" heel that’s designed for steadier walking, not just a formal look. The combination of a rubber non-slip outsole, a platform height, and a soft latex midsole is the core reason they’re worth considering.

Skip them if you’re shopping for maximum cushioning and support first, because this reads more like a mid-range “comfort-through-design” approach rather than something built to erase discomfort completely. And if you already know you can’t tolerate this heel height, you’ll probably be happier investing your budget elsewhere.
