Ocun have designed two versions of their velcro fastened performance shoe, the 'Ozone'. This is the 'Plus' version, which is best suited to wider feet. If you have a narrow foot shape take a look at the standard Ozone insead.
The Ocun Ozone Plus is built on a slightly asymmetic last (less asymmetric than the standard Ozone). This is typcially more suitable for wider foot types, particularly where this is combined with Morton's/Greek toe (where the second toe is the biggest). In such situations in can be difficult to find a high performance shoe that is not excrutiatingly painful, hence Ocun's decision to produce two versions of this shoe. The Ozone Plus has a mildly downturned profile which is useful for overhangs.
The Ozone Plus to have a snug, comfortable fit with minimal deadspace, which combined with the Vibram XS-Grip rubber, ensures that the Ozone Plus is both precise and reliable on tiny footholds.
If you have wide feet, and are looking for a reasonably priced high performance shoe then the Ozone is a winning bet. Narrow feet? Try the standard Ozone!
