For winter the additional factor in the choice of boot is the ability to fit
crampons. The most suitable for this purpose is a stiff-soled mountain boot
(leather or plastic) B2-3*. These enable any winter terrain to be covered from easy
walking to steep ice climbing and are a must for the serious winter mountaineer.
The disadvantages of these boots are that they may be used infrequently if
you are not an active mountaineer, they are twice the price, heavier and take
longer to break in than a summer boot.
If you don't have rigid-soled mountain boots a good quality walking boot
(B1-2*) will be adequate for this course. It should have; reasonably stiff uppers (not
canvas or Gore-Tex), providing enough ankle and foot support for traversing
relatively steep slopes, a reinforced toe cap (for kicking steps into hard snow),
and a reasonably stiff sole which can only be bent a few degrees when you try
to fold the toe up. There should be a hard rubber sole with good tread i.e.
Flexible walkers' crampons can be fitted to these boots and will ensure
that snow and ice such as that found in the Welsh mountains on a winter walk
can be negotiated safely.
