Arch support is nice as well. The instructions were clear on how to connect them. Cool store to shop at. I have flat feet and have had plantar fasciitis in the past. These are cute, Im not sure if they will be comfortable because the sizing is WAY off and Ill have to exchange. I hope the manufacturer reads this and replaces these cheap, awful anchors with ones that can actually take a hammer without bending and breaking. I notice battery drains fast 15 minutes went down 100%- 70%. Al año de comprado empezó a fallar el cargador, compré uno de imitación, que venden en Amazon (no venden el original) y calienta el reloj. Well done and thank you! Ive tried wireless, and corded.
