To use these Naot Dynasty sandals, simply put your feet in and adjust the hook - and - loop closure to your comfort level. They're great for both casual outings during the day and more relaxed evenings. When it comes to maintenance, keep them away from water as much as possible to preserve the suede on the footbed. You can use a soft brush to clean off any dirt on the straps. Since they're not slip - resistant, be careful when walking on wet or slippery surfaces. Also, as the footbed is non - removable, avoid getting it extremely dirty. If you're a half - size, remember to size up for the best fit.
