My husband needed waterproof boots so I purchased "<a data-hook="product-link-linked" class="a-link-normal" href="/Men-s-Columbia-Drylight-4-mm-Neoprene-Pull-on-Boots-Black/dp/B0040LWRNI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Men's Columbia Drylight 4 mm Neoprene Pull - on Boots Black</a>" (they actually ARE waterproof).  He liked the boots but they were really hard to remove so I looked for a boot puller to help him out.  I couldn't find any that were recommended for the type of boot he needed to use them on but I did find several reviews for other products that said they didn't work on that type of boot.  I decided to try this product and it works great!  Much easier than trying to remove pull-on above the calf boots by hand.  FootMatters shipped it out quickly, also a plus.
