Distinguishing features: precise, firm and structured. No compromise in the search for performance. The "Miura" holds the ultimate 'all-around' solution to the extreme requirements of modern climbing: friction, sensitivity, precision on edges and comfortable fit. The point of the "Miura" is derived from the "Mirage" and is very aggressive and extremely effective on small foot holds, pockets, and in cracks. Plus Structured shoe made from single piece leather. Maximum precision on small holds and heel hooks. Anticipated lacing to allow for extra precision during the hood. Double tension trim to guarantee maximum support for the foot. Fitting - While it isnt a black or white issue, a general rule dictates that soft shoes require a tighter fit, two to three sizes smaller than your street shoe size. We recommend you fit your trad shoes one to two sizes under your street shoe size. A thick midsole creates a platform on which you stand, while a slip-lasted slipper-type shoe relies on your crammed toes to create an edging platform. Once you determine your needs, try on several boots in that genre. Different last types fit different feet -- that's why we make lots of lasts. If it feels good, it probably is. Remember to factor in stretch. Unlined slip-lasted shoes tend to stretch a bit more than lined shoes -- about one full size. Lined shoes stretch about a half size. Remember: a well-fit comfortable shoe will work better than an ill-fitting tighter shoe.
