PositiveLoves the Boston 12 though it isn't for everyone: less soft and bouncy than the Endorphin Speed, but its stiffness and geometry suit their feet on long runs, where it disappears once they lock into a pace.

PositiveAn underpronator who likes the Boston 12 for long runs and tempo work, though they wouldn't pick it for recovery runs.

PositiveMatt Klein, Nathan and David call it a major improvement over v10 and v11: softer, bouncier and lighter, and great for workouts and long rhythmic runs. They criticize the upper for poor midfoot lockdown on turns, scratchy mesh and thin heel padding. It is now a true neutral shoe and less stable than before.

PositiveA 170 lb runner averaging 50 miles a week has hit 1,000 miles in the Boston 12 and calls it their favourite shoe: comfortable, nicely cushioned for long runs and light. The only downside is laces that come undone.

PositiveAbout 75 miles in and really enjoying them for long, easy and tempo runs as a way to avoid carbon plates in training; very different from the Boston 8/9.

PositiveThe best all-round shoe they've tried in years, pairing with the Adios Pro 3 for 18-24 mile long runs and faster tempos; not an easy-day shoe, and the Lightstrike Pro needs 20-30 miles to break in.

PositiveLoves it for every run short of spike workouts, including long runs up to 25K, where it feels more consistent than the Deviate Nitro 2.
Most runners find the Boston 12 firm and very durable, with a grippy outsole that lasts many hundreds of kilometres. It suits tempo and faster running better than easy days, and many need a break-in period. The main complaint is heel slip and poor lockdown from the upper and laces.
