I bought some Flyflot a few years ago and they were the most comfortable sandals/mules ever. I have thin feet but as these could be adjusted with velcro on both straps, they didn’t slip so ideal for the beach and even long walks. Unfortunately the shop in France don’t sell your brand anymore so I ordered 2 different pairs on your site. You don’t manufacture my former sandals anymore. The ones with 4cm heals I ordered only have 1 velcro strap fastening so my feet keep slipping forward (too big at front). It’s a shame because the inner soles are really comfortable but I just can’t walk far in them. I haven’t tried the 2nd pair yet with the higher heals but they seem OK. It would be great if you could manufacture the former mules with the 2 large velcro straps, easy to put on at the pool, beach and ideal for people who can’t where “normal” flip flops.
