On the run

Addiction GTS 15: Maximum support, built to last. Firm, very stable and dependable, with GuideRails support for heavy overpronation. Heavy and not very flexible, but it holds up to bigger runners and lots of miles.

Gel-Kayano 33: Comfort-first stability. Soft on landing at easy paces, with support that’s more gentle guidance than correction and a stiff, steady forefoot. It feels best slow, and at running pace some runners find it flat.

Specs side by side

Stack, drop and weight come from each brand’s own website. Numbers marked * aren’t published by the brand and come from other published specs. Weights are for the size each brand quotes. Expected life is our estimate.

Fit

Addiction GTS 15. Runs slightly short, so if you’re between sizes, go up a half. Plenty of room for custom orthotics. Narrow through extra-wide.

Gel-Kayano 33. True to size. The toebox tapers on the little-toe side, so it suits normal-width feet. Plush heel and tongue. Wide available.
