I looove this shoe. Very comfortable, wearable all day as long as you size it correctly. I don’t know if sizing has changed since Adidas bought 5.10, but you want to size them pretty snug, because it is an unlined leather shoe and will stretch almost a complete size. Once broken in, they are very comfortable and they are one of my favorite shoes. Ideal for crack climbing, slab/edging, or all day multi pitch.
