The Zensah Ankle Brace is stretchy and fits in Gr. S / M size to about 40 well. I have size 38.5 and narrow feet. The bandage can slip on easily. You do not fit perfectly and slipped even during extended wearing time of several hours. However, I think it is not suitable for walking long distances (walking, jogging), because the bandage applying on the soles. For short walks or normal walking, for example, when shopping, that's okay, at longer distances, however, created an unpleasant feeling of pressure on the sole, similar to socks that a slip in rubber boots. The bandage has the first wash survived in the machine at 30 ° C and was on a leash within 1 hour dry again. No sagging, no warping.
MY CONCLUSION: Well-fitting bandage with ankle problems - for hiking or walking long distances unsuitable.
