Warms my heart to see you wearing slippers. Having lived in Japan so long, I'm definitely a don't wear shoes inside kind of person.
I've helped my parents and friends move enough treadmills in my time to know how heavy those are and tough to move. Good job and pulling it in and getting it all setup. I hope it works well for you guys!
Thanks, I hope so too! I don't usually wear any shoes in the house, but with our dog having accidents here and there, slippers seem the best compromise!
