These are some of the comfiest sandals on Amazon — all on sale starting at $18

Available in over 40 colors and styles, these flip-flops are the no-pain, no-brainer companion your tootsies need for every season.

In case the idea of applying a snail secretion to your skin never crossed your mind, take it from thousands of Amazon shoppers — it's effective! This serum has amassed a cult-like following thanks to its lightweight, refreshing feel and hydrating, rejuvenating effects. Snail mucin not only helps boost collagen and elastin for a firmer look and feel, but it can also gently exfoliate for a smoother texture while also soothing the skin. Reviewers reported noticing everything from a brighter complexion to a reduction in the appearance of fine lines and dark spots after using. Good skin care can cost a bundle these days, so to find such a highly-rated product on sale for just $14 is a win in our book.

This classic top is available in nearly 30 colors and prints. Decisions, decisions! Plus, at just $24 (with the on-page coupon), this is close to as low as we've ever seen this 100% cotton top (it briefly dipped to $20 for Prime Day).

"I love the forgiving fit and the colors," raved one fan. "This shirt can be tucked, untucked, belted or tied. It can be a cover-up, worn with a shirt underneath and left unbuttoned or worn with leggings, shorts … needless to say, I’m having fun with this shirt and have hopes it will last a long time, as it appears sturdy and well made."

These sandals boast a flexible cork footbed and supple suede insole that contours to your foot with wear. See those adjustable straps? They're perfect for those with narrow or wide feet who need to customize their fit. Dr. Zaydenberg says they're a great pick for people with metatarsalgia (pain and inflammation in the ball of your foot) and plantar fasciitis.

"I bought these after my podiatrist recommended Birkenstock-style shoes," shared an Amazon shopper. "I only have a pair of regular-footbed Birkies to compare these to, but they are very similar in terms of the foot-shaped lining and arch support. They fit perfectly on my wide feet and did not hurt nearly as much to break in as real Birkies!"

Those flimsy flip-flops from last season won't do you any favors this summer, but these cushy sandals were designed with conditions like plantar fasciitis and arthritis in mind. They've got built-in arch support and shock-absorbing midsoles for relief, and their lightweight feel will put some pep in your step. 

Grab a pair in a neutral tone or a bright color like pink or orange .... all styles are deeply discounted!

People love these slippers for that walking-on-air feel, but they have another big asset: They're waterproof, so you can wear them to the pool, at the sauna or in the shower without damaging them. And their nonslip out soles will keep you stable even in the wettest situations. But there's plenty more to love about them — most importantly, their comfort factor. Their flexibility and molded-cushion footbed ensure you'll feel both cozy and supported — count on it! 

They're available in 29 colors ranging from basic black and brown to popping purples and pinks, though prices vary by color.

These cute kicks feature polyester straps with Velcro, including a backstrap, that are supersoft against the skin. The sandals are fully adjustable thanks to the hook-and-loop straps, so you can find your ideal fit and not worry about them slipping or sliding. They also have a contoured footbed for comfort, a durable rubber sole and are quick-drying, great for wearing to the beach and pool without worrying about getting them wet. 

These rugged waterproof sandals are so popular, they have earned themselves over 18,000 five-star reviews on Amazon. It’s easy to see why — not only do they feature a metatomical footbed that offers ample arch support, but they also boast a molded EVA midsole that customers say is as comfortable as their favorite pair of running shoes. The cushioned sandals also have a closed-toe design to protect your feet from the elements, a bungee lace capture system to help you create a custom fit and a durable rubber outsole that provides excellent traction, making them a sturdy option for a day on the trails. 

"These are the ultimate sandals for outdoor adventures. I've worn them crossing streams in the Grand Canyon, navigating shell-strewn beaches in the Northeast and scrambling over wet rocks on kayaking trips. Mine have lasted over 10 years and remain as strong and sturdy as the day I bought them," says Commerce Editor Janelle Randazza.

These highly rated sandals (over 3,400 five-star reviews on Amazon) are easy to put on and take off — no zippers or buckles here — and they're mega-stretchy too, so they won't dig into the sides of your feet. And did we mention how stylish these go-anywhere, budget-friendly kicks are? "I've had women stop me on the street to ask who makes these sandals! They are more classic stylish than trendy," says our Senior Beauty Editor, Jennifer Romolini.

These sleek sandals feature a cushioned foam footbed that is made from the same material as your favorite soft yoga mat (yes, really). They also boast straps that are made with 100% recycled polyester and a durable rubber outsole that has a rugged bottom for extra traction. Grab a pair while they're up to 30% off.

A loyal fan of eight years wrote: "I own this flip-flop in every color they make. I can walk miles in them with no problems. They are extremely comfortable. I once took a trip to Europe, took two different pairs of these shoes and by the end of the trip, had walked over 200 miles, all in this exact brand and style of flip-flop. And both pairs were still going strong."

Looking for comfortable walking sandals you can go for miles in? Thousands of shoppers recommend this option from Chaco. The criss-crossing straps and toe loop keep your foot in place, while the brand’s patented Luvseat technology provides "durability, daylong comfort, and arch support." The ChacoGrip outsoles have 3.0 mm lug depth, so you don’t have to worry about slipping and sliding and they have an adjustable lock buckle at ankle, so you can find your perfect fit.

I can personally attest to the quality of these comfy Sketchers picks — I wore 'em for up to 12 hours a day on a 10-day adventure through Italy, and had no complaints! Even after long, long days of walking the streets of Rome, Florence and Milan, these sandals were perfect for staying cool and comfortable while pounding the pavement, and I definitely noticed the difference when I had to swap over to my other, closed-toed shoes. They're so cushioned and supportive, and felt so sturdy that it never seemed like they'd come flying off my feet even when we were hustling between our destinations.
