LinkedIn Crossclimb #820 is a 4-letter Crossclimb ladder from FOOT to PATH. Phase one is crossword solving: 5 middle clues yield BOOT, BOOS, BOTS, BOTH, BATH. Phase two is ordering; phase three unlocks the combo ends tied by "A compound word for a narrow walkway used by pedestrians and not vehicles.".
Middle phase answers: "Type of shoe that extends up the lower leg to offer more protection" = BOOT; "Protesting sounds heard after a controversial sports call" = BOOS; "Software programs that crawl the web to analyze web pages" = BOTS; "Best of ___ worlds (enjoy two things simultaneously)" = BOTH; "Relaxing soak in a tub" = BATH.
Ordering phase: the valid middle chain is BOOT → BOOS → BOTS → BOTH → BATH. This permutation is the only valid one-letter chain for these answers.
Link FOOT → BOOT: F→B at the first letter (FOOT → BOOT) (combo-adjacent).
Link BOOT → BOOS: T→S at the fourth letter (BOOT → BOOS).
Link BOOS → BOTS: O→T at the third letter (BOOS → BOTS).
Link BOTS → BOTH: S→H at the fourth letter (BOTS → BOTH).
Link BOTH → BATH: O→A at the second letter (BOTH → BATH).
Link BATH → PATH: B→P at the first letter (BATH → PATH) (combo-adjacent).
Complete ladder: FOOT → BOOT → BOOS → BOTS → BOTH → BATH → PATH. The combo clue "A compound word for a narrow walkway used by pedestrians and not vehicles." describes both end words together — "FOOT" and "PATH" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt. Pattern: unique middle order — Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
