Sizing: watch my video! Comfort & gait: read below!
Just a bit more on size to accompany the video: it's hard when you look at the sneaker to understand why the Fuel Cell size 6 wide may fit better, but I realized that the shape of the toe box for the Fuel Cell is just a little rounder than the Vongo which is pointier. So maybe to accommodate the wide size, the whole top section of the Vongo is widened and it becomes too wide for me. Where for the Fuel Cell - because it's already naturally, a rounder shape - the wide doesn't widen the whole top section of the shoe too much and it fits so well for a wide foot.Comfort & gait: When it comes to comfort and gait, the Fuel Cell is surprisingly supportive and comfortable. I have been wearing the Vongos for a couple years without complaint. I guess sometimes you don't realize what you're missing until you actually try something different. But I also realize that sometimes when I was really tired or I walked longer, that I would be plodding along in the Vongo.When I wear the Fuel Cell, however, even though it isn't meant to propel gait in any way as far as I know, I find that this shoe and the way the sole is designed does something to help lighten, or propel, the gait a bit. What I mean is that it allows my fast-paced walking with my dog to be a lighter gait without feeling like a cumbersome walk. The Vongos weren't entirely that way, but sometimes it felt like my walking was heavier. I just assumed it was because I had my custom orthotics in the Vongo and although I would love to be a Barefoot sneaker wearer, I just haven't done the work, and with customer Orthotics I couldn't for the moment.So I naturally assumed that traditional sneakers are just stiffer and do create a heavier gait, but until I wore the Fuel Cell shoes, I realized that may not always have to be the case: my gait and the way I walk is just so easy, comfortable, and supported with the Fuel Cell.Lastly, when taking miles long walks on uphill/downhill trails (vs sidewalk), I tighten the laces on the Fuel Cell snugly, slide the 'lock thing' in place and tie a small bow on top of the 'lock.' If I don't tie a little bow, the lock seems to loosen a bit on my right foot, thereby loosening the shoe's fit.I'm aware that my gait is off, as many individuals' gait may be, so my opinions are coming from this perspective, wearing custom orthodics to correct over pronation, & someone who walks miles (off and on road) with a dog. :)
