I have purchased Ruff Wear Grip Trex shoes for my dogs, but at 60$ for a set of four I have decided that they are just too much to spend. They also just don't fit that well and cause blisters on my dogs feet. So I am going to create my own and I will describe my process here for anyone else who wants to do the same.
I will be doing something similar to this: DIY cool and cheap little dog sneakers or boots from duct tape
The first part of making the shoes is to create molds of the dogs feet. Luki and Kasimir both have the same width foot on their back feet 2.5 in., but both of their front left feet are smaller (2.75 and 2.83 in.) than their front right (2.91). To make the molds I am going to wrap gauze around the foot and "gorilla" tape over the entire foot 5 in. past the last pad. I will cut down the back of the foot until I can get their feet out and "gorilla" tape the slit shut. I will be putting in "great stuff" window and door sealant inside as i go. This will harden and make the mold. I will be using the foam/gauze/"gorilla" tape as the actual mold rather than just using the foam as the mold. The reason I want to do this is to allow a little space for the lining that I will be using (I'm not sure what fabric is going to work best yet). I found a soft fabric at Walmart that seemed durable with a harder back for the running shoe lining and I will probably use fleece when I make winter boots.
To make the shoes I will cut the fabric in an hourglass shaped pattern (as best I can) so that it is basically one piece and will lay this over the mold. Then I will "gorilla" tape over the fabric and mold. I am going to cut slits like the Instructable above and rather than using shoe laces I am going to use round elastic cord so that the shoes can flex. Since my dogs love to go rollerblading (full speed all the time) I will need a sturdy bottom for the shoes where they put most of their weight when running. I found some old firehose at work and took the inner lining out which consists of a flexible rubber with a dense woven fabric attached to it. I'm going to cut out enough to bend slighty up over the toes (using the tread wear of my "Grip Trex" shoes as an example). I'm will "gorilla" tape this to the bottom and the dogs will just wear through the tape in the places that they put the most pressure. The rest of the tape should hold the tread on. I plan on putting the rubber side down.
The winter boots will be done the same way just longer. I will use fleece or that sherpa fabric as a lining.
I will keep everyone posted as I do this project as to what works and what doesn't (maybe pictures as well). Stay Tuned.
If you have any suggestions I would love to hear them.
