Can smooth-tread boots still be used?
Perhaps casually, but not where route-appropriate traction is needed.
What does a collapsed midsole feel like?
Uneven, tilted or less stable, with poor recovery.
Is sole separation repairable?
Sometimes; construction and damage extent decide.
Does leakage require replacement?
First rule out collar entry and care issues, then assess repairability.
Put the advice into practice
Compare used boots with a stable pair on stairs and a side slope; note tread confidence, compression, lateral lean and separation.
Limits and cautions
Gradual decline can feel normal until compared with a stable baseline.
Replace for lost traction, collapsed structure, separation, persistent leakage or uncorrectable fitânot cosmetic scuffs alone.
