Design: They feature spring-loaded massage knobs that apply pressure to specific points on the soles of your feet. Usage: These are therapeutic sandals rather than everyday footwear; the manufacturer recommends wearing them for only 5–15 minutes per session. Experience: It is common to feel significant discomfort or soreness during the first few uses as the knobs stretch tense plantar muscles. Wearing socks can help you adjust to the sensation.
