(1) Note. Patents in this subclass disclose such work-related activities as, for example, roof climbing (i.e., having specific portions on the shoe to grip the roof or compensate for its inclination), or painting (i.e., having means on the shoe with which to apply paint), or gardening.

This subclass is indented under subclass 113. Foot covering intended to be worn while the wearer thereof is participating in physically active sports activities; or a member that is auxiliary to a foot covering worn for sports activities, which member adds a function related to the sports activity, but not itself having a foot-covering function.
(1) Note. Patents including a sports-related shoe accessory will be found in subclasses 132+ below. Patents including a shoe accessory not related to sports activities will be found in subclasses 136+ below.
(2) Note. In the schedule of subclasses indented hereunder will be found subclasses pertaining to a shoe used in one of several particularly-named athletic activities. The differences between shoes found in each of the named subclasses are not necessarily large differences, but they are significant when considered in light of the special requirements peculiar to each of the named activities. The weight of the shoe, the material of which it is made, the design and placement of the spikes or cleats used to give
traction or stability to the wearer, and the provision of means for fastening the shoe to the wearer or to equipment used in the particular activity, are all factors inherent in the design of a shoe intended for that athletic sport. This is not to imply that a shoe intended for a particular activity may not be worn for another activity, but does indicate that the differences between subclasses and shoes found therein are more than named differences, they are significant to the athletic activity for which the shoe is intended to be worn.

This subclass is indented under subclass 114. Foot covering intended to be worn while the wearer thereof is participating in sports activities wherein the wearer's foot covering has motion with respect to the surface that the foot covering contacts and is supported by.

This subclass is indented under subclass 115. Foot covering intended to be worn while moving over a surface that is not stable, that is, the particles or molecules that form the surface can move relative to each other.
(1) Note. Patents in this subclass disclose shoes intended to be worn while "walking" on water or sand.
(1) Note. Patents in this subclass usually disclose a boot that is especially padded to retain the boot on the foot, or having a filling of foam to insulate the wearer's foot as well as retain the boot on the foot. Such patents are found here rather than in subclass 93 above because the function of the filling is for retention of the ski boot on the wearer rather than for support of the foot.
