RHIZAL Brio Slip-On, Cowhide (Mens)
Hair-on calfskin upper, cow leather lining, a water buffalo leather sole and a copper earthing plug. That's the whole materials list, and the maker says the shoes have no synthetic rubber-plastic outsole, which is a good start. The open question is the leather: finished leather often carries an acrylic or polyurethane topcoat, and undyed isn't the same as uncoated. Nobody states the finish on the upper, the lining or the sole. The insole, the stitching thread and the glue aren't named either, and all of them sit against your foot.
Not listed, so not linked.
- Caveat
- Unknown: the finish and tanning of the upper, lining and sole leather, the insole, the stitching thread, the adhesive or sole attachment, any heel or toe stiffeners, any elastic panels, and what holds the copper plug in. Packaging not checked. Made to order, so the photos may differ from the pair you receive.
- Unverified
- Still unverified, and being researched with the maker: upper; lining; outsole; insole; thread; glue and sole attachment; heel counter and toe puff; elastic panels.
