cicada summer sandals The cicada sandal has a leather upper and sole. Soft, supple leather in a very open and airy style perfect for the heat of summer. A roomy fit, the sandal almost feels like you are wearing nothing! The sole is sturdy but flexible and we have tried and tested to avoid any rubbing or discomfort. Sizes are true however if you are a borderline 39/40 then we recommend a 39 as the width is not a restricted fit.* oddly fun!
