Water Shoes for Men & Women for $7.99 AC on Amazon
Amazon has some cool water shoes[amazon.com] for half off, just in time for summer where I live. They're $7.99 when you apply coupon code 50EFEAPS at checkout. There are four different colors in a range of sizes, and the coupon code works for all of them. I was also offered a $1 digital credit on checkout.
They're flexible and breathable, but the soles are still strong enough to protect feet.
