I purchased these shoes in December from a sports store on Rakuten Ichiba, intending to use them on my home treadmill. I used them for about 10 minutes, but they didn't seem to work well with my treadmill, so I've decided to sell them. They are like new, but please be aware that they have been used on a treadmill for about 10 minutes before purchasing. If you're okay with regular mail, I can lower the price by 1000 yen. The GEL-NIMBUS 27 is lightweight and offers excellent cushioning, providing a comfortable running experience. - Model Name: GEL-NIMBUS 27 - Size: 26.0 cm - Type: Running Shoes
