Cute dogs also love daily walks in life. This set of Vibrant Fellow soft skid-proof mesh boots will act as a good partner for them, providing traction and protecting the paws in daily environment. The whole boot is very soft with the flexible cuff at the top. Please kindly bend the cuff down outwards to put on the boots, and then recover the cuff after getting the boots on. Then fasten the boot by this adjustable strap, capable to prevent slipping off and supply a tightness. Finally, adjust the boot on paws slightly, and it will fit OK. Kindly Attention: Though the soles are waterproof, the boots can't be applied in deep water or in sands, because there may be water or fine sand seepage through sewing holes or through mesh fabric. For storage, please keep the boots in a dry, dark, and relatively cool place. The boots upper is slightly springy, so please measure across the whole paw pad to get the greatest measure of paw width and length, incl the toe, nail and hair. Size Small: Inner Sole Length 2.36", Inner Sole Width 2.17".
