Here's what other sites are saying:
The Pro climbing shoe from Mammut is a very precise and comfortable lace-up shoe. A good compromise between performance and comfort for longer routes! IMPORTANT NOTE: Mammut uses a UK sizing system. The shoe box will display the UK size, as will the sales tag, however; on the inside of the shoe there will be a tag or a sticker indicating the US size, which is always one size larger than the UK size. For example: The shoe box and sales tag will say 8 (this is the UK size) while the sticker on the inside will indicate that the US size is 9. Shoes are listed based on US sizing.

The Pro from Mammut is the perfect all-rounder climbing shoe; use for pockets, edging, cracks or slabs. Synthetic leather fabric minimizes stretch; cotton liner. Soft midsole delivers edging power, while still helping you grab holds with your toes on steep ground. Vibram rubber sole is super-grippy for maximum friction. Exclusive molded sole provides extra bite on heel hooks. On sizing, please note climbing shoe sizes are only a suggestion as fit is highly personal. Foot shape, use, and style all play into size selection.
