I really like the fit and support of these for my super wide, high-arched feet. The 12-2E is the best fit I've found in a tennis shoe.
They are stable and surprisingly fast thanks to the moderate heel drop and low-to-the-ground feel in the forefoot. Compared to my Gel 9s, not quite as comfy in the forefoot, locked-down, or quick, but definitely more stable.
A PowerStep bridge insole helped the cushioning up front and overall foot support. I've been wearing Gel Res 2-E for years because of their combo of durability and support despite them being too narrow and shallow for my feet.
Fit and stability so good on these CT Rallys that I bought a second pair (Green and White colorway) at retail.
I've put about 4 hours on them and the uppers are still breaking in, but I can feel them getting better and better.
