Shoe Conditions

First, look at the overall condition and shape of the shoe, and see if there are visible damages in the structure. You can also look at the rubber soles to gather insight into how often the sneakers were worn before you purchased them, the soles are a good indicator of how used the shoes are.

A solid rubber sole is the best choice because it is an indicator of high quality and perhaps a short wear life, worn-down, and flexible soles are not recommended because they will not provide the structure and support your feet need. In relation, also check the insoles for moisture, but in my opinion, you should opt to swap the insoles of all second-hand shoes you acquire, also make sure to try on the shoe in-store to make sure they fit properly since you are unsure where they come from and the standard shoe sizing changes with the continents.

Buying second-hand shoes that have been worn for a long time could also have an affect your foot position and movement. Over time, shoes adapt to the previous owner's foot shape and gait pattern. If the sole or footbed is already badly worn, this can impair your own natural movement and possibly lead to poor posture or discomfort. Therefore, always make sure to buy second-hand shoes that are in good condition or have hardly been worn. The risk is generally lower, especially with sturdy shoes such as boots or leather shoes.

If you’re considering buying second-hand shoes, make sure check that the sole is still intact, the footbed is not overly deformed, and that they feel comfortable and do not restrict your movement!

Leather shoes

Leather shoes and leather fashion are great options because of the durability of leather and the fact this material gets better the more worn it gets. The surface of leather can also come in diverse finishes but generally, it's simple to clean with some alcohol.

Buying second-hand leather not only gives the animal-derived product another chance at being utilized but also ensures the material can be used until the end of its extended lifecycle.

Kids shoes

Children quickly grow out of clothing and shoes, but should you buy second-hand shoes for your little ones? The answer: It depends on the shoe. Due to children's sensitive and developing health it is recommended to stay away from second-hand because it can affect the anatomic structure of children's growing feet. However, soft sole baby shoes, slippers, and pool flip-flops can be passed down because these shoes are not made for long-term support and are easy to wash and disinfect.

Hygiene and Health

Arguably the most important condition for second-hand footwear is the overall hygiene and cleanness you give your shoes after you have purchased them. Wearing used footwear can put you at risk of contracting diseases like athlete's foot and nail fungus, these typically like to inhibit moist, warm, and dark places, just like inside your shoes. To avoid wearing shoes with contagious bacteria, make sure to clean the shoes thoroughly inside and outside with Marseille soap and some warm water, after letting them air dry in the sun.
