I lost about 50 pounds (245 to 195) and my old brands felt too clunky but I tend to get a bit sloppy when I'm tired and my knees are a bit beat up from running at 240 to 250 pounds. Cloudflyers have made a hige difference. Even doing 13 miles at race pace in the cold I felt better than I did in other brands even at this weight.
For me they are the perfect combo of lightweight and support.
Definitely my new go to for now, we'll see if that lasts when I up my distance come Summer
