These are the boots you've been waiting for. Very rugged and sturdy, but most importantly, they stay on!! No more trying to find lost boots. Keep in mind, these boots have three closure systems so it takes a few minutes to put them on, but that's the last you have to worry about them until you take them off. You wouldn't use these for a walk around the block, but at the off leash park they are perfect. Winter boots are made of 600 D PVC, lined with 14oz fleece and sole has waxed leather for extra durability. All weather boots provide protection and have all the same features but without the fleece lining. Sizes Medium, Large and X-Large Winter boots $112 for a set of 4, or $30 individually. All weather boots $114 for a set of 4, or $31 individually.
