I made those lovely knitfelted house slippers, made with Lana Grossa Feltro wool in purble, grey and yellow. Please note the slippers are slightly different each.
 
The sole is made safe by adding little dots of sock stop, which should prevent you from sliding on slippery surfaces, such as wood floors or tiles.
 
The shoe lats your can see on the photos are not included. However, the lats are size 7 (41). The lenth of the slipper from tip to heel is ca 28cm and about 11 cm at the widest part across.
