I used to be over 220lbs. (see photo). Ive bought flutter sleeves from discount mail order catalogs and have been VERY disappointed in the quality of the fabrics used . It zips closed securely and has a nice elastic wrist strap that is super convenient for people like me who lose everything! Will update star ratings after using it for a few months. No need to drill it into the garage floor, so we can move them around if we need to. They can tighten the shoe somewhat though if you feel that are too lose. Ive been wearing the last pair I bought more or less every day around the house and garden, and have washed them quite a lot under hot water, sometimes using soap or detergent, and they lasted 10 months. After a lot of research on the carious styles of adidas ?slides?, the ?aqua slides? were exactly what i wanted and expected. but if i was to do it over again i would prolly go with one of those roll up solid rubber mats with the same design.
