An attachment to a mobility aid, such as a walker, wheeled walker or rollator, or wheelchair that automatically positions a slip resistant surface under the foot of the user. The distance the slip resistant surface is from the mobility aid is adjustable to suit the user. A retractable slip resistant surface attachment is removably attached to sides of the mobility aid. A sliding channel bracket is slidably attached to an attachment panel permitting the sliding channel bracket to be adjusted longitudinally. A slide panel with slide members captured by the sliding channel bracket permits an attached slip resist surface to move freely back and forth with a retraction mechanism. Adjustable, secure footing is obtained on wet or slippery surfaces preventing falls.
