Gone are the days of bulky water boots thanks to Amazon’s best-selling, light-as-a-sock Viffuur Water Sports Shoes ($8 to $10 a pair). Available in more than 40 colors and patterns in adult and child sizes, the retailer's shoppers swear by the slip-on water shoes.

And today only, Amazon has marked down the price by 20 percent, making it the perfect excuse to add a pair or two to your cart!

Some readers love these so much, they wear them around the house, too. "I purchased these with the intention of wearing them kayaking. They've become my favorite house shoe. I couldn't take them off after trying them on. They were so comfortable and fit so well," explained one fan.

The rubber-soled shoes are made with a breathable fabric that provides a comfortable yet secure fit. Its smooth design prevents chafing and makes it convenient to slip on and take off.

"They are extremely comfortable, which is rare for me to say about shoes in general cause my feet are super flat, and fit great," said a happy customer, who got a pair for a vacation.

From yoga to beach trips, swimming and fishing, Amazon shoppers deem this water shoe a versatile must-have for adults and kids.

"Love these shoes!!!" raved a water workout enthusiast. "Water aerobics and water yoga are so much more enjoyable. No scraping feet on the pool bottom and weightless! I have tried every kind of ‘water shoe’ over the last 30 years... These are the best."

Another customer, who is a fan of the shoes, plans to order a pair for each family member. "I bought these for a Caribbean cruise. They are perfect!!!!!" wrote the loyalist. "Fairly easy to get your foot into which is a huge plus if you have ever used water shoes. They dry quickly and have a thin rubber sole that is perfect for any beach, jet ski, canoe or kayak activities!"

One outdoors enthusiast put them to the test while kayaking. "I bought these for my two kids and myself for kayaking, and they... held up amazing. I have been through so many water shoes trying to protect my feet from rocks and the sun and find ones that dry out quickly with not a lot of success. But these shoes are awesome," explained the reviewer. "They are so comfortable and keep your feet from getting burnt while out on the paddle boards or fishing next to the water. They also dry out in no time."
