Thats a problem because I bought them for house slippers and I like to only use slippers inside my house. Good product at a reasonable price The fabric on the toe wore out extremely fast. Great bike for the price. The speaker plays along well and sounds like a good investment. Think Roach and Brown, Ammons and Stitt, Blakey, Silver, Mingus, Ellington, Gillespie, Monk, Peterson, Davis, Coltrane, Coleman, Green, Montgomery, Hubbard, Shorter, etc. And if I ever find Im out of toilet paper, I can always have a pair of extra rolls on the pull up bar. I have not charged the speaker since I received it and has worked almost 15 hours already and not discharged yet. This is way too long for my current set up. The value you get is spectacular.
