Trekking Sock

Since I had been working feverishly on the Frost Flowers shawl recently finished, I don't have much to share with you. Fortunately, I have taken to working on a sock for a commuting project, so I will be sharing my current sock with you. I recently bought some red tweedy Trekking XXL sock yarn. I have never worked with Trekking before and wanted to try the yarn. I decided that rather than follow any pattern I would make up my own. I was curious to see if what I call star decrease toe (I could have the name wrong, you decrease say every 7 stitches around the toe, then 6, then 5, etc) could work on a toe up, so that was my starting point. It was pretty easy to make this type of toe toe up. I just started with a provisional cast on, which at the end, I will take the tail of Trekking yarn and draw through the provisional loops. I increased until I had 9 stitches per increase area and then I found a couple of 9 stitch patterns to use. (You can't see the stitch patterns very well in the photo on the left, but if you click on it to make it bigger you may be able to see them better). When I came to the heel flap I decided I wanted to do something in a nine stitch grouping so that the stitch patterns have something defining underneath them, I decided therefore, to do a "standard" heel flap for 9 stitches (slip stitch rib?) and then for 9 stitches I did a slip stitch moss stitch type flap, then I alternated for the rest of the flap. I like the way it looks IRL, though, again, the photo doesn't quite illustrate. My problem is that I am bored now with the sock. I still have much leg to go, I have to figure out a cuff, and worst of all, the sock doesn't quite fit right. I can get it on, and it feels fine once one, but getting over the heel requires a struggle.

The question is, should I tear out way back to the gusset increases so that I can add more and make a longer heel flap which I think would make the sock fit easier, or do I leave this sock as it is and when I make it match make the gusset longer, etc.? I am leaning towards the second solution personally. What do you all think?
