Size Selection Guidelines

KuaiLu flip flops are styled in US standard sizes. Selecting the correct size ensures that the orthotic arch support curve aligns perfectly with your arches:

Sizes 6-7
Fits Narrow/True Fits
Sizes 8-9
Fits Medium Widths
Sizes 10-12
Fits Wide/Roomy Fits

Plantar Fasciitis Relief Study

The dense foam arch support absorbs landing impact forces and guides the foot through an optimal heel-to-toe gait. This reduces pulling forces on the plantar fascia ligament, leading to significant morning stiffness relief.

Summer Resort Durability

Engineered with light, water-resistant materials, these thong sandals are resistant to pool chlorine, saltwater, and summer heat, ensuring long-term utility across several seasons.
