Small Ally Zips by Treklite ("your ally in the woods") are cut a little fuller than the Thorngaiters and made of slightly less durable (but entirely adequate) materials. They have an easy on-off zipper down the calf, a generous ankle cuff, and "halfway-round" foam padding and elastic back. We currently have red or blue in stock. Size Small. Email for confirmation of availbility. If you have a large calf ask about the wide version. See sizing chart.
