Reduce only where it helps.
F1 is not simply “thinner D7.” Its direction begins with faster sessions and reassigns each zone from there.

T0 series F1
Fast sessions.
Less bulk.
F1 is T0 Lab's training-first concept: a leaner silhouette, more open midfoot structure and a restrained green signature. Final specifications will follow physical sampling.

F1 / Intervals
Fast changes, less visual bulk.
The F1 direction starts with a leaner silhouette, open midfoot zones and a precise cuff signature for high-output sessions.
Make the signature functional.
The green cue stays inside the cuff so the white product body remains quiet.
Sample before claims.
Final fibers, measurements and fit language stay open until the physical F1 sample is tested.
Next prototype
What F1 needs
to solve next.
The concept is clear. The next step is turning that direction into a physical sock worth testing.
Keep the white crew profile technical without turning it into a padded daily sock.
Place ventilation around the top and middle of the foot, then confirm it through wear testing.
Test whether the heel stays settled through fast direction changes without over-tightening the cuff.
Keep the identity inside the cuff so the body stays mostly white.
