roller skates

Things like electric skateboards and folding electric scooters may be good forms of last-mile transit, but they can be a bit of a hassle to carry while on buses or trains. That's why a group of San Francisco and China-based entrepreneurs created Blizwheel ESkates.

Readers of a certain age may remember those old-school roller skates that were strapped on over top of the user’s regular shoes. Walk Wing takes the idea further, with strap-on skates that feature retractable rubber wheels.

Roller skating and inline skating are both well past their primes, but there's a new generation of skates that offers a simpler, more casual skating experience. The all-new On Wheelz skates take things strapless, using a step-in system quite like clipless bike pedals.

Ever find that you could use a little extra pep in your step when walking around? French startup Rollkers can help. The company offers a set of motor-powered "under shoes" that slide around your sneakers and give you a few extra mphs of forward momentum.
