Calluses are your hands adapting to golf. They're protective tissue that forms in response to repeated friction. Well-maintained calluses protect against blisters; neglected ones can crack, tear, or cause their own problems.
Healthy vs. Problem Calluses
A healthy golf callus is smooth, flexible, and evenly thick. It provides a protective layer without excessive bulk. A problem callus is rough, rigid, overly thick, or has sharp edges. Problem calluses can crack deeply, catch on grip material, or cause blisters themselves.
Callus Maintenance
Maintain calluses after showers when skin is soft. Use a pumice stone or callus file to smooth rough spots and reduce excessive thickness. Don't try to remove calluses entirely — just keep them smooth and flexible.
Moisturize regularly to maintain flexibility. Dry, rigid calluses crack under stress. Well-hydrated calluses flex with your grip and provide consistent protection.
Heavy callus work the night before a round can leave skin tender. Do maintenance regularly rather than major work right before you play.
