ALTRA Womens Solstice XT 2 Cross Training Shoe

I'm on an eternal search for a pair of shoes that feel good and actually fit me. I've gotten fittings done in stores and been told that my left foot is Wide, but my right foot is Double Wide and that I have high arches that contribute to a "high volume" foot. I used to prefer Skechers for the Goga Mat insole, but over time Skechers seems to have gotten progressively more narrow and my feet possibly wider as well. I moved on to New Balance since they're a well known brand and I was told that their shoes typically run wider than other brands. This is true! BUT, not all of their "Wide" shoes are created equal. Certain models have wider toe boxes and E or EE width doesn't always mean a specific number value in mm or inches wide, so width is inconsistent with the labeling. In my most recent endeavor to find the perfect shoe, I've purchased the White New Balance 857 in 6.5 XX-Wide and the Altra Solstice XT in 6.5 in the only width available. You can see how the widths compare to other shoes I own in the photo I've included in my review. The widest shoe in the lineup is the New Balance 880 in Blue (#6) or the New Balance 1080 (#4). Despite being DOUBLE Wide, the 857 is one of the most narrow feeling shoes in my photo. I think this is a combination between an obviously more narrow toe box and the leather material making it feel stiffer and like it's exerting more pressure on my feet vs the softer mesh materials. The shoe furthest to the right (#7) is a size 6.5 Altra Solstice XT. As you can see, it's the smallest shoe in terms of length despite being the same size numerically speaking. It also has a wider toe box despite not actually coming in a "Wide" width. Unfortunately, it's also the shortest shoe vertically speaking. My foot was spilling out of the top, likely due to my high arches. This was not an issue with the other shoes in the photo BUT I do commonly have problems feeling like the shoe is tight regarding vertical space. And yes, it is a wider toe box but was still tight in width for my left foot which is a Wide and even tighter for my right foot which is Double Wide. I used to size up to get a slightly wider shoe, but it really sucks to do that with shoes used for gym workouts because I feel my feet sliding forward all the time. I still haven't found the perfect shoes, but from what I've tried so far I think my next move will either be to try a size up in the Altra Solstice XT (hoping that length, width, and height will improve with a size increase) or figure out which New Balance models are TRULY wider and not just labeled as such.
