Lots of equipment is stored by sticking it to the walls with what appears to be velcro and/or magnets.
Many supplies, particularly small items like nuts and bolts, are stored in clear baggies. - Most people have baggies and holsters with supplies attached to them as they make their way through the space station.
One guy in particular likes to use his legs to carry equipment as he floats through the station. (If you're not using them for walking, why not? It frees up your arms to keep you from bumping into things.)
It is not unusual for them to spend time cataloging, storing, labeling, and/or looking for a particular nut, bolt, cable, or pair of gloves... The other day a missing piece of equipment was finally found floating in the middle of a room.
Everyone wears socks on the Space Station, not shoes. The men all seem to wear solid colored socks (black, white, gray) and Sandy's socks are more... interesting. - It's hard to get a good picture of them because she flies by so quickly!
* I did a search to see if Sandy was known for having an odd collection of socks, and it turns out she lost the pink, blue, and white striped socks during her last visit to the station, and just found them again a few days ago.
