Cycling shoe to a standard cycling shoe. Riivo, Bont, DMT, Suplest, and Exustar offer track-specific shoes. The traditional cycling tourist usually used toe clips and straps, but touring shoes designed for use with clipless pedals are now also common, usually with a recessed cleat so that the rider can both walk and cycle effectively. Touring shoes typically sacrifice some rigidity for traction and add treads. This type of shoe generally has a soft outsole (as compared with a road shoe) and a molded internal midsole. They are shaped more like a street or trail shoe with a less exaggerated "rocker" allowing a
Intensive pig farming Pigs have a limited tolerance to high temperatures and heat stress can lead to death. Maintaining a more specific temperature within the pig-tolerance range also maximizes growth and growth-to-feed ratio. Indoor piggeries have allowed pig farming to be undertaken in countries or areas with unsuitable climate or soil for outdoor pig raising. In an intensive operation, pigs will no longer need access to a wallow (mud), which is their natural cooling mechanism. Intensive piggeries control temperature through ventilation or drip water systems. Pigs are naturally omnivorous and are generally fed a combination of grains and protein sources (soybeans, or meat
