Seasonal foot care need
Many buyers purchase specifically for summer when wearing sandals (frequent mentions of summer season and heel/sole concerns). The product aligns with warm-weather routines.
Active lifestyle & callused feet
Customers report buying due to occupational or exercise demands (dancers, standing jobs, frequent walking) that cause hardened skin and calluses. The product is marketed as effective for high-wear feet.
Repeat/loyal repurchase
Numerous reviews explicitly state 'repeat purchase,' 'second/third/fourth time buying,' or 'consistent restock.' This indicates strong customer retention and satisfaction-driven loyalty.
Influencer/social recommendation
References to TikTok expectations and friend recommendations suggest social media and peer influence drive initial trial, though some mention expectations are not immediately met.
Price advantage over Japanese brands
Multiple reviewers note this product is cheaper than Japanese drugstore alternatives (¥1,500 comparisons cited) while delivering similar results, making value a purchase driver.
