Always Love 'Em!

My partner and I have purchased these from a local retailer before, and we both instantly fell in love with them! He loves the freedom on his cheeks, and I love seeing the cheeks!🥰

Due to lack of styles/colors in the store we usually go to, I ordered them this time directly from the website. Prices were similar to in-store and shipping was free for the size of my order, which is especially appealing and gave me reason to buy just one more pair of a different/cheaper style to hit the price point. Well worth it! Everything arrived on time, looks and fits just like the last pairs we'd purchased. Over all pleased!

I do recommend sizing up one (possibly just US customers if Canada sizing is a bit different 🤷‍♀️). Luckily our local shop was able to recommend this in person - online first time shoppers, be aware!
