Training kit
A sock changes the fit inside the shoe. Check its shape, seams and drying behaviour as part of the footwear combination.

Choose a size that places the heel panel under your heel without pulling the toe area tight. Excess fabric can bunch, while a sock that is too small may drag across the toes. Smooth it into place before putting on the shoe rather than trying to correct folds through the upper.
Check the toe seam and any reinforced areas. They should not sit where they create uncomfortable pressure. A seamless label does not guarantee comfort for every foot, so judge the actual construction. If you have reduced sensation or a medical foot-care plan, follow individual advice rather than relying on how a sock feels during a quick try-on.
A padded sock takes up more room. Try it with the shoe you will use, and check toe space and pressure over the top of the foot. Do not assume extra cushioning will improve a shoe that is already tight. A thinner sock may change the fit, but it is not a solution to an unsuitable shoe shape.
Consider the height of the cuff against the shoe collar. A low sock that slips below the collar can leave skin rubbing against the upper. A high cuff should stay in place without feeling restrictive. Notice whether the sock rotates or slides during normal walking before using it in a longer session.
Read the fibre and washing information, but avoid choosing only by a material's reputation. Construction and thickness also affect drying and comfort. Follow the care label, including any restrictions on heat, and check whether the sock has shrunk or lost its shape after washing.
Change out of wet socks and dry shoes appropriately between uses. Keeping a spare pair in the bag can be useful when the journey is wet or the session leaves clothing damp. Store the spare separately from used kit.
Inspect heels and toes for thinning, holes and hardened seams. Replacing a worn pair may be more useful than adding another insole to compensate for discomfort. If rubbing or skin problems continue, address the footwear combination and seek advice when needed rather than assuming thicker socks are always the answer.
