Ellgy Plus Cracked Heel Cream, $19
Why this is a must-have:
Flip-flops are great for summer, but the heat and constant walking can dry out the skin on your heels, causing cracked heels and pain. Ellgy Cracked Heel Cream uses a unique intensive dual moisturising system that works both on and below the surface of your skin. It contains saccharide isomerate, a complex that retains moisture in your skin, preventing it from drying out and cracking, and portulaca extract, an essential fatty acid that strengthens the epidermal layer of your skin. The result? Long-lasting protection and hydration for your feet.

Available at Guardian, Unity, Watsons, selected pharmacies, beauty shops and medical halls.
