Here are a few practical tips:
Choose a safe surface. Check the ground for sharp objects, thorns, broken glass, hot surfaces, and other hazards before removing your shoes.
Start gradually. If you usually wear shoes throughout the day, your feet may need time to adapt to unfamiliar surfaces.
Avoid unsafe environments. Do not walk barefoot where there may be contaminated soil, animal waste, or hidden debris.
Protect your feet when necessary. People with diabetes, peripheral neuropathy, poor circulation, a history of foot ulcers, or reduced sensation should seek appropriate medical guidance before attempting barefoot walking. A small cut or burn may go unnoticed and develop into a more serious problem.
Do not force the practice. If barefoot walking is uncomfortable, wearing suitable footwear is perfectly reasonable. There is no need to endure pain to obtain a supposed grounding benefit.
Keep your expectations realistic. Treat earthing as an optional outdoor activity rather than a substitute for medical treatment.
