Froddo's Gym Shoes are some of the most durable kids barefoot shoes around! They will last all season long and some! Fresh new colors are here! These minimalist shoes have a zero-drop, flexible sole with a natural foot-shaped toe box. Included in the shoe are two removable insoles for a customized fit. By removing either one or both of the inserts, you can have a more barefoot shoe for your child and increase the width of the shoe. These shoes open up very wide to help children with high volume feet fit in the shoe without a struggle. Froddo's shoes also work very well for kid's with narrow heels and they will stay on their feet! Froddo produces their shoes using quality natural products and skilled, ethical labor to produce their shoes. The result is a high-quality, comfortable shoe that shows off the craftsmanship that Froddo prides themselves on. All of Froddo's shoes are chrome-free. The leather is vegetable tanned which makes them a great natural barefoot choice. My Personal Advice: To keep your leather Froddo Shoes looking their best- treat them well with a natural leather oil- this product works well. Froddo shoes may seem stiff out of the box; however, with just some wear the soles and the upper soft up like butter. The 2 removeable insoles makes the shoes great for adjusting width and some length. Not Suitable for kids with very wide or high volume feet.
