Many pregnant women are comfortable sleeping on their stomach during the first week of their pregnancy, especially if they usually sleep on their stomach. But it can become uncomfortable once your uterus starts expanding and you begin to feel like you are carrying a large beach ball on your stomach.
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.
Molded cleats and interchangeable cleats are best for natural grass surfaces where you need shoes to bite into the ground for traction. Indoor shoes are best for gym floors, sport courts, asphalt and concrete. This leaves turf shoes, which are designed specifically for turf-covered fields.
