I only use it before I go to sleep. I like thong style so the fit is perfect. I bought a pair of similar sandals last year for my husband. So I contacted Amazon to contact the SELLER then received an email from SELLER who told me to contact AMAZON. I purchased a trainer for my recumbent trike so I can ride my trike indoors during our rainy and cold winter months. Where the Samson excels is in two areas:* Controls* Headphone jack. The velcro band makes adjusting to your foot or size thickness easy. Luckily all my gems came and are still all intact. Even though the bottom of the shoes are flat but if the heels are too small you have to wear them like the regular high heels - very easy to spring your ankles when walk on uneven surface. Decent quality runs a little small but a good sweatshirt overall.
